Preemptive treatment in the acute and early subacute phase of uncomplicated type B aortic dissections with poor prognosis factors.

Objective: Due to its favorable outcome regarding late morbidity and mortality, thoracic endovascular repair (TEVAR) is becoming more popular for uncomplicated type B aortic dissection (TBAD). This study aimed to compare preemptive endovascular treatment and optimal medical treatment (OMT) and OMT alone in patients presenting uncomplicated TBAD with predictors of aortic progression. Design: Retrospective multicenter study. Methods: We analyzed patients with uncomplicated TBAD and risk factors of progression in two French academic centers. Aortic events [defined as aortic-related (re)intervention or aortic-related death after initial hospitalization], postoperative complications, non-aortic events, and radiologic aortic progression and remodeling were recorded and analyzed. Analysis was performed on an intention-to-treat basis. Results: Between 2011 and 2021, preemptive endovascular procedures at the acute and early subacute phase (<30 days) were performed on 24 patients (group 1) and OMT alone on 26 patients (group 2). With a mean follow-up of 38.08 ± 24.53 months, aortic events occurred in 20.83% of patients from group 1 and 61.54% of patients from group 2 (p < .001). No patient presented aortic-related death during follow-up. There were no differences in postoperative events (p = 1.00) and non-aortic events (p = 1.00). OMT patients had significantly more aneurysmal progression of the thoracic aorta (p < .001) and maximal aortic diameter (p < .001). Aortic remodeling was found in 91.67% of patients in group 1 and 42.31% of patients in group 2 (p < .001). A subgroup analysis of patients in group 1 showed that patients treated with preemptive TEVAR and STABILISE had reduced maximum aortic diameters at the 1-year (p = .010) and last follow-up (p = .030) compared to those in patients treated with preemptive TEVAR alone. Conclusion: Preemptive treatment of uncomplicated TBAD with risk factors of progression reduces the risk of long-term aortic events. Over 60% of medically treated patients will require intervention during follow-up, with no benefit in terms of postoperative events. Even after surgical treatment, patients in the OMT group had significantly more aneurysmal progression, along with poorer aortic remodeling.

Percutaneous coronary intervention versus optimal medical therapy for stable coronary artery disease: An umbrella review.

Background: Invasive management of stable coronary artery disease is still a controversial topic. The purpose of this umbrella review was to synthesize systematic reviews (SRs) that evaluate the benefits and harms of percutaneous coronary intervention (PCI) versus optimal medical therapy (OMT) in patients with stable coronary artery disease. Methods: We systematically searched PubMed/MEDLINE, Embase, and CENTRAL from 2018 to August 7, 2022. We included SRs with meta-analyses of randomized controlled trials (RCTs) that evaluated the question of interest. We assessed the methodological quality of the SRs with the AMSTAR-2 tool. We summarized the results of the outcomes for each SR. We calculated the degree of overlap of the RCTs included in the SRs using the corrected covered area (CCA). Results: We found 10 SRs with meta-analyses. The SRs included 3 to 15 RCTs. The degree of overlap among the SRs was very high (CCA > 15%). No SR evaluated the certainty of the evidence using the GRADE system and 9 out of 10 had critically low methodological quality. The SRs reported heterogeneous results for the outcomes of all-cause mortality, myocardial infarction, revascularization, and angina. On the other hand, for the outcomes of cardiovascular mortality and stroke, all SRs agreed that there were no differences between PCI and OMT alone. Conclusions: We found 10 SRs on the use of PCI compared to OMT alone for patients with stable coronary artery disease. However, none had high methodological quality, none evaluated the certainty of the evidence using the GRADE approach, and the results were inconsistent for several outcomes. This variability in evidence may result in divergent clinical decisions for the management of stable coronary artery disease among healthcare professionals. It is necessary to perform a high-quality SR using the GRADE approach to clarify the balance of benefits and harms of PCI.

High Non-Cardiac Death Incidence Should Be a Limitation of Drug-Eluting Stents Implantation? Insights from Recent Randomized Data.

Despite the introduction of drug-eluting stents (DES) significantly improved the efficacy and safety of percutaneous coronary interventions (PCI), particularly in a high-risk group of patients, the gap between PCI with his competitor's coronary artery bypass surgery (CABG) and/or optimal medical treatment alone was not reduced. In this revision, we highlighted the fact that in recent years landmark randomized studies reported at mid and long-term follow-ups a high incidence of non-cardiac death, cancer incidence, or both in the DES group of patients. The overall incidence of non-cardiac death was significantly higher in the DES vs. the comparator arm: 5.5% and 3.8%, respectively, p = 0.000018, and non-cardiac death appears to be more divergent between DES vs. the comparator at the extended follow-up to expenses of the last one. One of these trials reported five times greater cancer incidence in the DES arm at late follow-up, 5% vs. 0.7% p < 0.0018. We review the potential reason for these unexpected findings, although we can discard that DES biology could be involved in it. Until all these issues are resolved, we propose that DES implantation should be tailored accorded patient age, life expectancy, and lesion complexity.

Thoracic Endovascular Aortic Repair versus Optimal Medical Treatment in Patients with Type B Intramural Hematoma: A Meta-Analysis.

PURPOSE: We intended to study the effect of thoracic endovascular aortic repair (TEVAR) and optimal medical treatment (OMT) on type B intramural hematoma (BIMH). METHODS: We searched PubMed, EMbase, Cochrane Library, and China National Knowledge Infrastructure databases that compared TEVAR and OMT in patients with BIMH. Two authors independently assessed the risk of bias using the Newcastle-Ottawa Scale. The rate ratio (RR) and 95% confidence interval were used to calculate the outcome. The primary endpoints were aortic-related death and regression/resolution. Secondary endpoints were all-cause death, progression to dissection, and secondary intervention. RESULTS: Eight observational studies were included in the analysis. TEVAR reduced aortic-related death (RR 0.22, 95% CI 0.08-0.56, P = 0.002, I² = 24%) and promoted hematoma regression/resolution (RR 1.48, 95% CI 1.05-2.10, P <0.05, I² = 71%) compared to OMT. Moreover, TEVAR was associated with a reduction in progression to dissection (RR 0.32, 95% CI 0.13-0.81, P <0.02, I² = 39%) and secondary intervention (RR 0.18, 95% CI 0.09-0.37, P <0.00001, I² = 38%) compared to OMT. However, all-cause death has no significant difference between the two groups (RR 0.45, 95% CI 0.17-1.19, P = 0.11, I² = 58%). CONCLUSIONS: The results of this meta-analysis suggested that TEVAR is an effective treatment for BIMH, which can delay the progression of intramural hematoma and promotes regression/resolution. More research about indications of TEVAR is still needed.

Optimal medical treatment versus endovascular aortic repair in uncomplicated isolated abdominal aortic dissection.

OBJECTIVE: To report the results of optimal medical treatment (OMT) and endovascular aortic repair (EVAR) in patients with uncomplicated isolated abdominal aortic dissection (IAAD). METHODS: A retrospective review of 96 consecutive patients with uncomplicated IAAD (uIAAD) managed at a single tertiary vascular unit between January 2011 and July 2021 was conducted. Standard methods for univariate and survival analyses were used. The primary outcomes were all-cause mortality. Secondary end points included uIAAD progression, interventional complications, and follow-up aortic intervention. RESULTS: Initially, 53.1% of patients (51/96) were managed with OMT. No in-hospital deaths occurred. During follow-up, three patients died, and three and two patients who were initially managed with OMT subsequently required endovascular treatment and surgical management, respectively. Initially, 46.9% of patients (45/96) underwent EVAR. One patient died during hospital admission; nine patients had an endoleak after operation and one needed reintervention. Furthermore, during follow-up, five patients died; four patients needed reoperation, one surgery and three endovascular treatments. The overall long-term mortality was 8.4%, and follow-up aortic intervention rate was 9.5% (median follow-up, 54 months; interquartile range, 33-81 months) with no significant difference between groups. Of note, 12 patients (12.6%) suffered uIAAD progression, which was higher in the OMT group than EVAR group (10 [19.6%] vs 2 [4.5%]; P = .03). CONCLUSIONS: uIAAD may be managed safely by OMT with regular surveillance, despite the risk of disease progression. Compared with OMT, EVAR could significantly prevent uIAAD progression. For anatomically suitable patients with uIAAD progression and who are unresponsive to OMT, pre-emptive EVAR is a safe and feasible option.

Global Longitudinal Strain is Incremental to Left Ventricular Ejection Fraction for the Prediction of Outcome in Optimally Treated Dilated Cardiomyopathy Patients.

Background Speckle tracking echocardiographic global longitudinal strain (GLS) predicts outcome in patients with new onset heart failure. Still, its incremental value on top of left ventricular ejection fraction (LVEF) in patients with nonischemic, nonvalvular dilated cardiomyopathy (DCM) after optimal heart failure treatment remains unknown. Methods and Results Patients with DCM were included at the outpatient clinics of 2 centers in the Netherlands and Italy. The prognostic value of 2-dimensional speckle tracking echocardiographic global longitudinal strain was evaluated when being on optimal heart failure medication for at least 6 months. Outcome was defined as the combination of sudden or cardiac death, life-threatening arrhythmias, and heart failure hospitalization. A total of 323 patients with DCM (66% men, age 55±14 years) were included. The mean LVEF was 42%±11% and mean GLS after optimal heart failure treatment was -15%±4%. Twenty percent (64/323) of all patients reached the primary outcome after optimal heart failure treatment (median follow-up of 6[4-9] years). New York Heart Association class ≥3, LVEF, and GLS remained associated with the outcome in the multivariable-adjusted model (New York Heart Association class: hazard ratio [HR], 3.43; 95% CI, 1.49-7.90, P=0.004; LVEF: HR, 2.13; 95% CI, 1.11-4.10, P=0.024; GLS: HR, 2.24; 95% CI, 1.18-4.29, P=0.015), whereas left ventricular end-diastolic diameter index, left atrial volume index, and delta GLS were not. The addition of GLS to New York Heart Association class and LVEF improved the goodness of fit (log likelihood ratio test P<0.001) and discrimination (Harrell's C 0.703). Conclusions Within this bicenter study, GLS emerged as an independent and incremental predictor of adverse outcome, which exceeded LVEF in patients with optimally treated DCM. This presses the need to routinely include GLS in the echocardiographic follow-up of DCM.

Frailty Among Patients With Acute ST-Elevation Myocardial Infarction in the United States: The Impact of the Primary Percutaneous Coronary Intervention on In-Hospital Outcomes.

OBJECTIVES: To determine the average treatment effect (ATE) of primary percutaneous coronary intervention (pPCI) versus medical treatment (MT) on in-hospital outcomes across the spectrum of frailty in patients with ST-elevation myocardial infarction (STEMI). METHODS: Adult patients hospitalized for STEMI between October 2015 until December 2017 from the National Inpatient Sample (NIS) database were retrospectively analyzed and stratified by the Hospital Frailty Risk Score into low, intermediate, and high frailty risk subgroups. Propensity score matching analysis was performed to estimate the ATE of pPCI in each frailty subgroup. The primary outcome was all-cause in-hospital death. RESULTS: A total of 429,070 patients were included in the final analysis, with 28.4% at an increased frailty risk. Frail patients were significantly less likely to receive pPCI (85.6%, 47.2%, and 22.6% for low, intermediate, and high frailty risk groups). Rates of adverse in-hospital events including death, cerebrovascular event, and major bleeding were significantly higher in patients with increased frailty risk. pPCI was associated with a significant reduction of in-hospital death in low (-8.0%), intermediate (-14.6%), and high (-14.7%) frailty subgroups, compared to MT (P<.001). CONCLUSIONS: pPCI was associated with reduced rates of in-hospital death in patients with frailty presenting with STEMI. These findings suggest a benefit of pPCI in this complex patient population, although based on observational data. Long-term effects and safety need to be investigated in future studies.

Single center experience in the treatment of hemodynamically significant diffuse coronary artery disease of the left anterior descending.

INTRODUCTION: To date there are no recommendations on how to treat patients with an FFR positive but diffusely diseased left anterior descending coronary artery (LAD). Benefit of coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) is not so evident due to doubts regarding longevity and patency. METHODS: This retrospective single-center study assessed clinical outcomes in patients presenting with symptomatic single vessel coronary artery disease of a diffusely diseased, hemodynamically significant LAD treated by coronary artery bypass grafting (CABG) or optimal medical therapy (OMT) between 2015 and 2020. Primary outcome of this study was the composite endpoint of all-cause mortality, myocardial infarction and repeat revascularization during 2-year follow-up. Secondary endpoints consisted of the individual components of the primary endpoint. Change in angina severity grade based on the Canadian Cardiovascular Society (CCS) class between baseline and 2-year follow-up was assessed. RESULTS: Fifty-nine patients were included of which 25 patients underwent CABG and 34 patients were treated by OMT. There was a statistically significant difference in FFR value at baseline between the treatment groups (CABG 0.70 ± 0.04; OMT 0.75 ± 0.04; p < 0.001). After 2-year follow-up, there were no statistically significant differences with regard to the primary endpoint (CABG 16% (n = 4); OMT 17.6% (n = 6); p = 1.00) and secondary endpoints between the groups over 2-year follow-up. CONCLUSION: In patients with hemodynamically significant diffuse single vessel coronary artery disease of the left anterior descending, there was no difference between OMT and CABG in terms of mortality, myocardial infarction, revascularization and symptom reduction after two years of follow-up.

Long-term results of type B aortic dissection patients with tumor after endovascular repair or optimal medical therapy: a single-center and retrospective cohort study.

BACKGROUND: The effect of thoracic endovascular aortic repair (TEVAR) for acute Type B aortic has been confirmed, However, when patients with malignant disease suffer from acute type B aortic dissection (ATBAD), the effect of TEVAR intervention is still unclear. METHODS: ATBAD patients were identified from electronic medical records between 2009 and 2019. The 5 year overall and aortic-disease free survival rates were analyzed and compared between the two groups. RESULTS: Of the 40 enrolled patients, 27 (67.5%) received TEVAR and 13 (32.5%) received OMT. The baseline characteristics of the two groups were not significantly different. Kaplan‒Meier survival curve showed that the 5 year overall survival and 5 year aortic-disease free survival of the TEVAR group were better than those of the OMT group. The Cox proportional hazard model with unadjusted risk showed an 83.0% decrease in 5 year overall mortality (HR, 0.17; 95% CI, 0.05-0.56) and a lower aortic-disease related risk (HR, 0.08; 95% CI, 0.02-0.39) in TEVAR group compared to OMT group. After adjusted for age, gender, smoking, drinking and comorbidities (diabetes mellitus, hypertension and coronary artery diseases), the hazard ratio of 5 year overall mortality was 78.0% lower (HR, 0.22; 95% CI, 0.06.0.81) and the risk of aortic-disease related mortality was 93.0% lower (HR, 0.07; 95% CI, 0.01-0.61) in TEVAR group compared to OMT group. In the cohort stratified by age, sex, the risk of the 5 year overall or aortic-disease related mortality in TEVAR group was relatively reduced compared to OMT group. CONCLUSIONS: Compared to OMT, TEVAR improves the 5 year overall and aortic-disease free survival rates in the cohort of ATBAD patients with a single type of malignant tumors.

Gender Differences in the Medical Treatment of Peripheral Artery Disease.

BACKGROUND/OBJECTIVES: Peripheral arterial disease is a frequent and severe disease with high cardiovascular morbidity and mortality. However, female patients appear to be undertreated. OBJECTIVES: The primary goal was to compare the prescription of optimal medical treatment (OMT) of peripheral arterial disease between women and men in primary health care. MATERIAL AND METHODS: An observational retrospective study was based on the data collected from general practitioners (GP) office in Brittany. RESULTS: The study included 100 patients, aged 71 ± 10 years old, with 24% of women. Compared to men, women received the OMT less frequently (29.2% vs. 53.9%, p = 0.038), especially after 75 years old. Antiplatelet therapy was largely prescribed (100%), statins less frequently (70.8% women vs. 85.5% men), and prescription of renin-angiotensin-aldosterone system inhibitors was still not optimal in the two genders (41.7% women vs. 61.9% men). Active smoking is important for both women and men (33% and 30% respectively). CONCLUSION: Optimal medical treatment of peripheral artery disease is insufficiently prescribed, especially in women in this region of France.

Left ventricular remodelling and prognosis after discharge in new-onset acute heart failure with reduced ejection fraction.

AIMS: This study aimed to investigate the left ventricular (LV) remodelling and long-term prognosis of patients with new-onset acute heart failure (HF) with reduced ejection fraction who were pharmacologically managed and survived until hospital discharge. We compared patients with ischaemic and non-ischaemic aetiology. METHODS AND RESULTS: This cohort study consisted of 111 patients admitted with new-onset acute HF in the period 2008-2016 [62% non-ischaemic aetiology, 48% supported by inotropes, vasopressors, or short-term mechanical circulatory devices, and left ventricular ejection fraction (LVEF) at discharge 28% (interquartile range 22-34)]. LV dimensions, LVEF, and mitral valve regurgitation were used as markers for LV remodelling during up to 3 years of follow-up. Both patients with non-ischaemic and ischaemic HF had significant improvement in LVEF (P < 0.001 and P = 0.004, respectively) with significant higher improvement in those with non-ischaemic HF (17% vs. 6%, P < 0.001). Patients with non-ischaemic HF had reduction in LV end-diastolic and end-systolic diameters (6 and 10 mm, both P < 0.001), but this was not found in those with ischaemic HF [+3 mm (P = 0.09) and +2 mm (P = 0.07), respectively]. During a median follow-up of 4.6 years, 98 patients (88%) did not reach the composite endpoint of LV assist device implantation, heart transplantation, or all-cause mortality, with no difference between with ischaemic and non-ischaemic HF [hazard ratio 0.69 (95% confidence interval 0.19-2.45)]. CONCLUSIONS: Patients with new-onset acute HF with reduced ejection fraction discharged on optimal medical treatment have a good prognosis. We observed a considerable LV remodelling with improvement in LV function and dimensions, starting already at 6 months in patients with non-ischaemic HF but not in their ischaemic counterparts.

Clinical benefits of fast-track rehabilitation program for patients with uncomplicated type B acute aortic dissection.

OBJECTIVES: Uncomplicated type B acute aortic dissection (UTBAAD) has traditionally been treated medically. Although patients are treated based on the rehabilitation program established by the Japanese Circulation Society, we sometimes encounter patients with complications related to the long duration of bed rest. We performed novel fast-track rehabilitation for UTBAAD, which consisted of short-duration bed rest and the early initiation of walking under secure blood pressure control. METHODS AND RESULTS: From April 2009 to February 2017, there were 73 consecutive cases of UTBAAD. Conventional medical treatment was administered to 39 patients (group G) during the early period. From August 2013, 34 patients (group F) received our 'fast-track' rehabilitation program, which consisted of the following: oral intake and assuming a sitting position from day 1 after the onset, standing by the bed from day 2, walking in their room from day 4, and discharge from day 16 if all goes smoothly. Group F had a significantly earlier initiation of standing and walking, first defecation, and weaning from oxygen and intravenous antihypertensive agents than group G. The pneumonia complication rate was significantly lower in group F than in group G. The hospitalization duration was markedly shorter and the in-hospital expense lower in group F than in group G. There were no significant differences in the rate of late adverse aortic events within 12 months after onset. CONCLUSIONS: Our fast-track rehabilitation program for patients with UTBAAD resulted in a better in-hospital clinical course and lower expense than conventional medical treatment without any adverse aortic events.

Procedures for chronic total occlusion: when are they recommended and when not.

Coronary chronic total occlusion (CTO) produces an important clinical problem, often treated with medical therapy or coronary artery bypass grafting. Recent clinical studies, both registries and randomized trials, demonstrated that percutaneous coronary interventions (PCI), could provide a valid therapeutic option. Nonetheless, significant reduction in all-cause mortality, cardiac mortality, myocardial infarction, MACE, and MACCE has not been demonstrated in the subgroups analysis of randomized trials. These analyses suggest that PCI for CTO should be reserved for patients with angina or with large areas of the myocardium with reversible ischaemia. Large randomized studies should search for a personalized approach, considering the risks and complexity of PCI in CTO, which should mainly consider the extension of the ischaemia and the viability of the myocardium.

Analysis of secondary prevention measures implemented in patients with a history of acute coronary syndrome / Análisis de las medidas de prevención secundaria introducidas en pacientes con historia de síndrome coronario agudo

Abstract Objective: To determine the pharmacological measures implemented for secondary prevention in patients with acute coronary syndrome in order to identify whether the implemented management corresponds to recommended clinical practice guidelines and to intervene in those cases where incomplete treatments are found. Methods: A pre- and post-quasi-experimental study was performed in patients with acute coronary syndrome who were affiliated with the Colombian health system. The patients were monitored for one year from the occurrence of acute coronary syndrome, and all dispensed medications were reviewed. For those patients in whom a lack of a prescription ((-blockers + renin-angiotensin-aldosterone system inhibitors (RAASi) + dual antiaggregation + statin) was identified, an intervention was performed with their treating physicians, showing the analysis of each case, the missing medication, and the evidence supporting the recommendation. The results were measured three months later. Results: A total of 829 patients with acute coronary syndrome who underwent percutaneous coronary intervention (90.1%) or coronary bypass (9.9%) were identified. The mean age was 63.8 ± 10.6 years and 73.1% were men. The recommended pharmacological therapy was completed in 729 patients (87.9% of cases). The intervention performed on the remaining 100 patients was able to add the missing drug in 23.0% of the cases. Statistical analysis showed no significant differences with the drug that should have been initiated nor with the success of the intervention. Conclusion: The majority of patients with acute coronary syndrome are adequately treated after percutaneous intervention with medications recommended by the guidelines. Limited success in the adjustment of the management acute coronary syndrome was achieved following the recommendations given to the responsible physicians.

Resumen Objetivo: Determinar las medidas de prevención secundaria implementadas en pacientes que sufrieron un síndrome coronario agudo para identificar si corresponden con guías de práctica clínica e intervenir casos con tratamientos incompletos. Métodos: Estudio cuasiexperimental, antes y después, en todos los niveles de atención, en el que se incluyeron pacientes que sufrieron un síndrome coronario agudo, afiliados al sistema de salud de Colombia. Se hizo seguimiento un año (1 enero y 31 diciembre de 2014) a partir del episodio del síndrome coronario agudo y se revisó toda la medicación dispensada. En quienes se identificó falta de prescripción ((-bloqueadores + ISRAA + antiagregación dual + estatina) se realizó una intervención sobre sus médicos tratantes mostrando el análisis de cada caso, el medicamento faltante y la evidencia que avala la recomendación. Tres meses después se midieron los resultados. Resultados: Se hallaron 829 pacientes con síndrome coronario agudo sometidos a intervención coronaria percutánea (90,1%) o baipás coronario (9,9%). La media de edad fue 63,8 ± 10,6 años y 73,1% fueron hombres. La terapia farmacológica recomendada se cumplió en 729 pacientes (87,9% de casos). La intervención hecha sobre los 100 pacientes restantes logró que agregaran el fármaco faltante en 23,0% de casos. El análisis estadístico no mostró diferencias significativas con el fármaco que debía iniciarse ni con el éxito de la intervención. Conclusión: La mayoría de pacientes que sufrieron un síndrome coronario agudo están tratados de manera adecuada después de la intervención percutánea, con medicamentos recomendados por las guías. Se logró un limitado éxito en el ajuste del manejo tras las recomendaciones dadas a los médicos responsables.

Utilización de fármacos antihipertensivos, efectividad e inercia clínica en pacientes / Antihypertensive drug use, efficacy, and clinical inertia in patients

Resumen Introducción: la hipertensión arterial es una de las principales causas de enfermedad cardiovascular. Se encuentra una limitada caracterización local de su tratamiento en nuestra población. Metodología: estudio de corte transversal sobre la prescripción de fármacos antihipertensivos, la efectividad del tratamiento y la inercia clínica en pacientes atendidos en 2014. Se estableció la efectividad según el Sevent Report of the Joint National Committee y se definió inercia clínica como la falta de modificaciones para alcanzar la meta terapéutica. Se incluyeron variables sociodemográficas y farmacológicas. Se aplicaron modelos de regresión logística. Resultados: de un total de 4.195 pacientes, se obtuvo una muestra aleatoria de 309, el 54,7% eran mujeres y 52,8% tenían más de 60 años. Los antihipertensivos más utilizados fueron losartán e hidroclorotiazida (20,8% cada uno). Se halló un control de cifras tensionales en el 75,3% de un total de 675 consultas y de las 167 visitas que no presentaron control tensional se evidenció inercia clínica en 47,9%. Tener prescrito concomitantemente un antidiabético se asoció con menor probabilidad de que se presentara inercia clínica (p=0,032; OR: 0,21; IC95%: 0,051-0,879). Conclusión: la proporción de pacientes que no logran las metas de control de tensión arterial y la frecuencia de inercia clínica es menor que en otras series de pacientes.

Abstract Introduction: Arterial hypertension is one of the main causes of cardiovascular disease. The characteristics of its treatment in the population at a local level are relatively unknown. Methods: A cross-sectional study was conducted on the prescribing of antihypertensive drugs, the efficacy of the treatment, as well as the clinical inertia in patients seen in the year 2014. The efficacy was established according to the Seventh Report of the Joint National Committee, and clinical inertia was defined as lack of modifications to achieve the therapeutic aim. Sociodemographic and pharmacological variables were included in the logistical regression models. Results: Out of a total sample of 4,195 patients, a randomised sample of 309 patients was obtained, of which 54.7% were women, and 52.8% were over 60 years of age. The antihypertensive drugs most used were losartan and hydrochlorothiazide (20.8% each). Blood pressure control was observed in 75.3% of a total of 675 clinical visits, and of the 167 visits where the blood pressure was not controlled, there was evidence of clinical inertia in 47.9%. To have a concomitant antidiabetic drug prescribed was associated with a lower possibility of there being clinical inertia (P=.032; OR: 0.21; 95% CI: 0.051-0.879). Conclusion: The proportion of patients that do not achieve the targets of blood pressure control, as well as the frequency of clinical inertia, are lower than those found in other patient series.

Transcatheter vs. surgical aortic valve replacement and medical treatment : Systematic review and meta-analysis of randomized and non-randomized trials.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has emerged as the procedure of choice for patients with severe aortic stenosis (AS) and high perioperative risk. We performed a meta-analysis to compare the mortality related to TAVR with medical therapy (MT) and surgical aortic valve replacement (SAVR). METHODS: A systematic literature search was conducted by two independent investigators from the database inception to 30 December 2014. Relative risk (RR) and odds ratio (OR) were calculated and graphically displayed in forest plots. We used I 2 for heterogeneity (meta-regression) and Egger's regression test of asymmetry (funnel plots). RESULTS: We included 24 studies (n = 19 observational studies; n = 5 randomized controlled trials), with a total of 7356 patients in this meta-analysis. Mean age had a substantial negative impact on the long-term survival of AS patients (OR = 1.544; 95% CI: 1.25-1.90). Compared with MT, TAVR showed a statistically significant benefit for all-cause mortality at 12 months (OR = 0.68; 95% CI: 0.49-0.95). Both TAVR and SAVR were associated with better outcomes compared with MT. TAVR showed lower all-cause mortality over SAVR at 12 months (OR = 0.81; 95% CI: 0.68-0.97). The comparison between SAVR and TAVR at 2 years revealed no significant difference (OR = 1.09; 95% CI: 1.01-1.17). CONCLUSION: In AS, both TAVR and SAVR provide a superior prognosis to MT and, therefore, MT is not the preferred treatment option for AS. Furthermore, our data show that TAVR is associated with lower mortality at 12 months compared with SAVR. Further studies are warranted to compare the long-term outcome of TAVR versus SAVR beyond a 2-year follow-up period.

Percutaneous repair of mitral valve regurgitation in patients with severe heart failure: comparison with optimal medical treatment.

BACKGROUND: Occurrence of severe mitral valve (MV) regurgitation (MR) is an independent negative predictor of mortality in patients with severe systolic heart failure (HF). This study examines clinical effects and cardiac reverse remodelling in patients with severe systolic HF receiving percutaneous mitral valve repair (PMVR) using MitraClip in comparison to patients receiving optimal medical therapy only. METHODS: Between 2010 and 2014, 86 patients (Society of Thoracic Surgeons score: 10.5% ± 1.2%) with severe HF (left ventricular [LV] ejection fraction; LVEF: 25% ± 2%; LV endsystolic diameter [LVESD]: 55 ± 3 mm) and severe MR received PMVR using MitraClip. Cardiac reverse remodelling and clinical parameters were compared to HF patients with severe MR (from our HF outpatient clinic; n = 69; LVEF: 26% ± 1.4%; LVESD: 53 ± 2 mm) receiving optimal medical therapy (OMT) only. All patients received stable OMT and were characterised by echocardiography, 6-minwalk-distance test and cardiac biomarkers within a 24 months observation period. RESULTS: PMVR in patients with end-stage HF and severe MR resulted in reduction of MR and significant additional cardiac reverse remodelling (LVEF: 26 ± 1.4 vs. 33% ± 2%, p < .05; LVESD: 53 ± 2 vs. 47 ± 2 mm, p < .05) over the 24 months observation period as compared to pharmacologically-only managed comparators. CONCLUSIONS: Both OMT and PMVR cause cardiac reverse remodelling and relief of symptoms in patients with HF and severe MR. PMVR results in significant additional cardiac reverse remodelling compared to pharmacologically-only managed patients.

Stable coronary artery disease - medical treatment.

The crucial issues in optimal medical therapy to improve prognosis and reduce angina symptoms are secondary prevention, effective control of concomitant diseases, risk factors and medical treatment. In spite of successful percutaneous coronary interventions (PCI) and medical treatment with beta-blockers, ACE-inhibitors or angiotensin receptor blockers, statins and antiplatelet drugs, some patients are still symptomatic. In the era of PCI not sufficient attention is paid to other drugs reducing the incidence of angina episodes: calcium antagonists, long-acting nitrates, metabolic agents and novel antianginal drugs. Substantial part of secondary coronary interventions may be avoided if angina pectoris would be properly treated. In the light of the Courage and BARI trials' results, optimal medical therapy of angina pectoris remains important part of treatment.

Intestinal Microbiota-Generated Metabolite Trimethylamine-N-Oxide and 5-Year Mortality Risk in Stable Coronary Artery Disease: The Contributory Role of Intestinal Microbiota in a COURAGE-Like Patient Cohort.

BACKGROUND: Trimethylamine-N-oxide (TMAO), a metabolite derived from gut microbes and dietary phosphatidylcholine, is linked to both coronary artery disease pathogenesis and increased cardiovascular risks. The ability of plasma TMAO to predict 5-year mortality risk in patients with stable coronary artery disease has not been reported. This study examined the clinical prognostic value of TMAO in patients with stable coronary artery disease who met eligibility criteria for a patient cohort similar to that of the Clinical Outcomes Utilizing Revascularization and Aggressive Drug Evaluation (COURAGE) trial. METHODS AND RESULTS: We examined the relationship between fasting plasma TMAO and all-cause mortality over 5-year follow-up in sequential patients with stable coronary artery disease (n=2235) who underwent elective coronary angiography. We identified the COURAGE-like patient cohort as patients who had evidence of significant coronary artery stenosis and who were managed with optimal medical treatment. Higher plasma TMAO levels were associated with a 4-fold increased mortality risk. Following adjustments for traditional risk factors, high-sensitivity C-reactive protein, and estimated glomerular filtration rate, elevated TMAO levels remained predictive of 5-year all-cause mortality risk (quartile 4 versus 1, adjusted hazard ratio 1.95, 95% CI 1.33-2.86; P=0.003). TMAO remained predictive of incident mortality risk following cardiorenal and inflammatory biomarker adjustments to the model (adjusted hazard ratio 1.71, 95% CI 1.11-2.61; P=0.0138) and provided significant incremental prognostic value for all-cause mortality (net reclassification index 42.37%, P<0.001; improvement in area under receiver operator characteristic curve 70.6-73.76%, P<0.001). CONCLUSIONS: Elevated plasma TMAO levels portended higher long-term mortality risk among patients with stable coronary artery disease managed with optimal medical treatment.

Update in the management of type B aortic dissection.

Stanford type B aortic dissection (TBAD) is a life-threatening aortic disease. The initial management goal is to prevent aortic rupture, propagation of the dissection, and symptoms by reducing the heart rate and blood pressure. Uncomplicated TBAD patients require prompt medical management to prevent aortic dilatation or rupture during subsequent follow-up. Complicated TBAD patients require immediate invasive management to prevent death or injury caused by rupture or malperfusion. Recent developments in diagnosis and management have reduced mortality related to TBAD considerably. In particular, the introduction of thoracic stent-grafts has shifted the management from surgical to endovascular repair, contributing to a fourfold increase in early survival in complicated TBAD. Furthermore, endovascular repair is now considered in some uncomplicated TBAD patients in addition to optimal medical therapy. For more challenging aortic dissection patients with involvement of the aortic arch, hybrid approaches, combining open and endovascular repair, have had promising results. Regardless of the chosen management strategy, strict antihypertensive control should be administered to all TBAD patients in addition to close imaging surveillance. Future developments in stent-graft design, medical therapy, surgical and hybrid techniques, imaging, and genetic screening may improve the outcomes of TBAD patients even further. We present a comprehensive review of the recommended management strategy based on current evidence in the literature.
