When anticoagulation management in atrial fibrillation becomes difficult: Focus on chronic kidney disease, coagulation disorders, and cancer.

Anticoagulation therapy (AT) is fundamental in atrial fibrillation (AF) treatment but poses challenges in implementation, especially in AF populations with elevated thromboembolic and bleeding risks. Current guidelines emphasize the need to estimate and balance thrombosis and bleeding risks for all potential candidates of antithrombotic therapy. However, administering oral AT raises concerns in specific populations, such as those with chronic kidney disease (CKD), coagulation disorders, and cancer due to lack of robust data. These groups, excluded from large direct oral anticoagulants trials, rely on observational studies, prompting physicians to adopt individualized management strategies based on case-specific evaluations. The scarcity of evidence and specific guidelines underline the need for a tailored approach, emphasizing regular reassessment of risk factors and anticoagulation drug doses. This narrative review aims to summarize evidence and recommendations for challenging AF clinical scenarios, particularly in the long-term management of AT for patients with CKD, coagulation disorders, and cancer.

Revisiting Cardiovascular Benefits of Blood Pressure Reduction in Primary and Secondary Prevention: Focus on Targets and Residual Risk-A Systematic Review and Meta-Analysis.

BACKGROUND: Previous meta-analyses resurrected the debated statement "the lower, the better" following blood pressure (BP)-lowering treatment. We investigated the benefits of BP-lowering treatment at different BP targets by prevention category. METHODS: The meta-analysis protocol was registered at the International Prospective Register of Systematic Reviews (CRD42022379249). The database included 115 BP-lowering or comparison trials from patients with (n=241 089) or without (n=198 937) previous cardiovascular events. Prevention disease groups were stratified by in-treatment achieved BP, drug class versus placebo, and drug class versus other classes. Risk ratios and 95% CIs of major adverse cardiovascular events were calculated. RESULTS: Following a standard (10/5 mm Hg) BP reduction, major adverse cardiovascular event relative risk reductions were not different between prevention groups (primary, 25% [95% CI, 18%-31%]; secondary, 28% [95% CI, 20%-37%]). For achieved systolic BP of at least 140 mm Hg, between 130 and 140 mm Hg, and <130 mm Hg (nadir, 125 mm Hg), (1) risk ratios of major adverse cardiovascular events and absolute risk reductions were not different between prevention groups across systolic BP strata, and (2) residual risk, though 4.1× greater in secondary than primary prevention, decreased in primary prevention from higher to lower systolic BP targets. The effect of separate drugs versus others on the primary outcome was not different between prevention groups. CONCLUSIONS: BP-lowering treatment benefits did not differ by prevention group to a nadir of 125 mm Hg for systolic BP. Although residual risk in secondary prevention is higher than in primary prevention, it gradually decreases at progressively lower systolic BP targets in primary prevention.

[Régurgitation mitrale sévère due à la sarcoïdose cardiaque : une présentation clinique inhabituelle ; une étude de cas et des recherches antérieures]. / Severe mitral regurgitation due to cardiac sarcoidosis : An unusual clinical presentation ; a case report and review of the literature.

Sarcoidosis is a granulomatous inflammatory disease that may involve multiple organ systems, including the heart. Cardiac manifestations are not rare and include atrial and ventricular arrhythmias, conduction abnormalities, congestive heart failure, valvular dysfunction, pericarditis, and sudden death. Although, cardiac sarcoidosis (CS) remains a diagnostic and therapeutic challenge. This article describes a case of a patient with a history of pulmonary sarcoidosis who presented with congestive heart failure, on the basis of severe mitral regurgitation secondary to cardiac infiltration and summarizes the published evidence regarding CS and mitral regurgitation.

One-year outcomes following a hypertensive urgency or emergency.

There are scarce data on the comparative prognosis between patients with hypertensive emergencies (HE), urgencies (HU), and those without HU or HE (HP). Our study aimed to compare cardiovascular (CV) outcomes of HE, HU, and HP during a 12-month follow-up period. The population consisted of 353 consecutive patients presenting with HE or HU in a third-care emergency department and subsequently referred to our hypertension center for follow-up. After both groups completed scheduled follow-up visits, patients with HU were matched one-to-one by age, sex, and hypertension history with HP who attended our hypertension center during the same period. Primary outcomes were 1) a recurrent hypertensive HU or HE event and 2) non-fatal CV events (coronary heart disease, stroke, heart failure, or CV interventions), while secondary outcomes were 1) all-cause death, 2) CV death, 3) non-CV death, and 4) any-cause hospitalization. Events were prospectively registered for all three groups. During the study period, 81 patients were excluded for not completing follow-up. Among eligible patients(HE = 94; HU = 178), a total of 90 hospitalizations and 14 deaths were recorded; HE registered greater CV morbidity when compared with HU (29 vs. 9, HR 3.43, 95 % CI 1.7-6.9, p = 0.001), and increased CV mortality (8 vs. 1, HR 13.2, 95 % CI 1.57-110.8, p = 0.017). When opposing HU to HP, events did not differ substantially. Cox regression models were adjusted for age, sex, CV and chronic kidney disease, diabetes mellitus, and smoking. During 1-year follow-up, the prognosis of HU was better than HE but not different compared to HP. These results highlight the need for improved care of HU and HE.

DASH vs. Mediterranean diet on a salt restriction background in adults with high normal blood pressure or grade 1 hypertension: A randomized controlled trial.

BACKGROUND & AIMS: Non-pharmacological measures are recommended as the first-line treatment for individuals with high-normal blood pressure (BP) or mild hypertension. Studies directly comparing the BP effects of the Dietary Approaches to Stop Hypertension (DASH) vs. the Mediterranean diet (MedDiet) on a salt restriction background are currently lacking. Thus, our purpose was to assess the BP effects of a 3-month intensive dietary intervention implementing salt restriction either alone or in the context of the DASH, and the MedDiet compared to no/minimal intervention in adults with high normal BP or grade 1 hypertension. METHODS: We randomly assigned never drug-treated individuals to a control group (CG, n = 60), a salt restriction group (SRG, n = 60), a DASH diet with salt restriction group (DDG, n = 60), or a MedDiet with salt restriction group (MDG, n = 60). The primary outcome was the attained office systolic BP difference among the randomized arms during follow-up. RESULTS: A total of 240 patients were enrolled, while 204 (85%) completed the study. According to the intention-to-treat analysis, compared to the CG, office and 24 h ambulatory systolic and diastolic BP were reduced in all intervention groups. A greater reduction in the mean office systolic BP was observed in the MDG compared to all other study groups (MDG vs. CG: mean difference = -15.1 mmHg; MDG vs. SRG: mean difference = -7.5 mmHg, and MDG vs. DDG: mean difference = -3.2 mmHg, all P-values <0.001). The DDG and the MDG did not differ concerning the office diastolic BP and the 24 h ambulatory systolic and diastolic BP; however, both diets were more efficient in BP-lowering compared to the SRG. CONCLUSIONS: On a background of salt restriction, the MedDiet was superior in office systolic BP-lowering, but the DASH and MedDiet reduced BP to an extent higher than salt restriction alone.

Sex-related cardiovascular prognosis in patients with hypertensive emergencies: a 12-month study.

Current evidence on the prognosis of patients with a hypertensive crisis and predisposing factors is limited. We registered the clinical phenotype of patients with HC admitted to the emergency department, while those with a hypertensive emergency (HE) were hospitalized. One-year outcomes, i.e., composite of death or cardiovascular hospitalizations, were determined in patients with HE after hospital discharge. Out of 38,589 patients assessed in the emergency department, 256 hypertensive urgencies and 97 HE was registered. After stratification of the HE by sex, 48 men and 46 women completed the one-year follow-up. Men had more events than women (27 vs. 13, Ηazard Ratio 2.2, 95% Confidence Interval 1.03-4.7, p = 0.042) after adjustment for age, cardiovascular or chronic kidney disease, and diabetes mellitus. Our study raises the hypothesis that the male sex is an independent risk factor for cardiovascular outcomes in HE patients. CV Cardiovascular, BP blood pressure. The diagram presents the groups of comparison, men versus women in hypertensive emergencies that completed the 1-year follow-up for outcomes, in terms of hospitalizations or deaths.

Fatty liver index and cardiovascular outcomes in never-treated hypertensive patients: a prospective cohort.

The prevalence of nonalcoholic fatty liver disease (NAFLD) has been increasing rapidly worldwide, affecting 25-30% of the population. Fatty liver index (FLI) is a validated marker of NAFLD and can be used as a screening tool for hepatic steatosis. The purpose of the study was to evaluate the relationship between FLI and the risk of major cardiovascular events in never treated hypertensive patients. We included 903 hypertensive patients without a history of cardiovascular disease (mean age 52.7 ± 11.4 years; men 55%; baseline clinic BP 149.8 ± 15.2/95.5 ± 10.1 mmHg). Participants were prospectively evaluated for a mean follow-up period of 5.2 ± 3.2 years with at least one annual visit. Patients were also categorized into two groups using an FLI of 60 units. The incidence of cardiovascular events during follow-up was 8.5% (n = 77). Patients with FLI < 60 (n = 625) had a better BP control compared to their counterparts with FLI ≥ 60 (n = 278) during follow up (43% vs 33%, p = 0.02). Cox-regression analysis indicated that FLI (Hazard Ratio [HR], 1.05; 95% Confidence Interval [CI], 1.03-1.07, p < 0.001), FLI z-scores (HR, 3.66; 95% CI, 2.22-6.04) and high-risk FLI (HR, 7.5; 95% CI, 3.12-18.04) were independent determinants of the outcome after adjustment for baseline and follow-up variables. Stratification by diabetes mellitus indicated that FLI predicted the outcome to a greater extent in those with than those without diabetes (P-interaction < 0.001). In conclusion, FLI has an independent prognostic value for the incidence of cardiovascular events in newly diagnosed, never-treated hypertensive patients. Therefore, FLI might identify higher-risk patients in the primary prevention of hypertension.

Chronic Thoracic Aortic Dissection: How to Treat, When to Intervene.

Thoracic aortic dissection (AD) is associated with increased morbidity and mortality. Acute aortic syndrome is the first presentation of the disease in most cases. While acute AD management follows concrete guidelines because of its urgent and life-threatening nature, chronic AD is usually overlooked, although it concerns a wide spectrum of patients surviving an acute event. Acute AD survivors ultimately enter a chronic aortic disease course. Patients with chronic thoracic AD (CTAD) require lifelong surveillance and a proportion of them may present with symptoms and late complications demanding further surgical or endovascular treatment. However, the available data concerning the management of CTAD is sparse in the literature. The management of patients with CTAD is challenging as far as determining the best medical therapy and deciding on intervention are concerned. Until recently, there were no guidelines or recommendations for imaging surveillance in patients with chronic AD. The diagnostic methods for imaging aortic diseases have been improved, while the data on new endovascular and surgical approaches has increased significantly. In this review, we summarize the current evidence in the diagnosis and management of CTAD and the latest recommendations for the surgical/endovascular aortic repair of CTAD.

Overview of salt restriction in the Dietary Approaches to Stop Hypertension (DASH) and the Mediterranean diet for blood pressure reduction.

Despite considerable advances in pharmacological treatments, hypertension remains a major cause of premature morbidity and mortality worldwide since elevated blood pressure (BP) adversely influences cardiovascular and renal outcomes. Accordingly, the current hypertension guidelines recommend the adoption of dietary modifications in all subjects with suboptimal BP levels. These modifications include salt intake reduction and a healthy diet, such as the Dietary Approaches to Stop Hypertension (DASH) diet or the Mediterranean diet (MedDiet), independently of the underlying antihypertensive drug treatment. However, dietary modifications for BP reduction in adults with prehypertension or hypertension are usually examined as stand-alone interventions and, to a lesser extent, in combination with other dietary changes. The purpose of the present review was to summarize the evidence regarding the BP effect of salt restriction in the context of the DASH diet and the MedDiet. We also summarize the literature regarding the effects of these dietary modifications when they are applied as the only intervention for BP reduction in adults with and without hypertension and the potent physiological mechanisms underlying their beneficial effects on BP levels. Available data of randomized controlled trials (RCTs) provided evidence about the significant BP-lowering effect of each one of these dietary strategies, especially among subjects with hypertension since they modulate various physiological mechanisms controlling BP. Salt reduction by 2.3 g per day in the DASH diet produces less than half of the effect on systolic blood pressure (SBP)/diastolic blood pressure (DBP) (-3.0/-1.6 mmHg) as it does without the DASH diet (-6.7/-3.5 mmHg). Although their combined effect is not fully additive, low sodium intake and the DASH diet produce higher SBP/DBP reduction (-8.9/-4.5 mmHg) than each of these dietary regimens alone. It is yet unsettled whether this finding is also true for salt reduction in the MedDiet.

Isolated diastolic vs. systolic hypertension phenotypes and outcomes: prospective cohort of newly diagnosed individuals with hypertension.

AIMS: To evaluate whether different hypertension phenotypes, namely, isolated systolic hypertension (ISH), isolated diastolic hypertension (IDH) and systolic/diastolic hypertension (SDH) have a differential outcome effect by clinic and ambulatory blood pressure (BP) measurements. METHODS: We prospectively evaluated in 569 never-treated patients with sustained hypertension (age 52.6 ±â€Š11.6 years; men 55%; clinic BP 150 ±â€Š15/95.5 ±â€Š10 mmHg, systolic/diastolic; 24-h ambulatory BP 128.9 ±â€Š12.6/80.6 ±â€Š9.7) the incidence of major cardiovascular (CV) events within 5 years, after adjustment for confounders, including the rate of BP control and the weighted follow-up BP. RESULTS: All participants received antihypertensive drug treatment (mean number of drugs 1.9 ±â€Š1.1; follow-up visits 4.6/patient). Average clinic BP achieved during follow-up was 136 ±â€Š12.6/83.9 ±â€Š9.4 mmHg, with 39% of participants having clinic BP less than 140/90 mmHg in at least 75% of their visits, and 24% in 25-75% of visits. Prevalence of hypertension phenotypes defined using BP differed from that using ambulatory BP, whereas integration of both BP measurements reclassified the initial phenotype to another in 18% of participants. Although, no differential outcome effect was observed between clinic IDH and SDH assessed using clinic or ambulatory BP measurements, clinic BP-based ISH was associated with a higher outcome incidence than the IDH and SDH phenotypes (hazard ratio 4.8, 95% confidence interval 1.4-17.0, P = 0.015). ISH diagnosed by integration of clinic and ambulatory BP, also increased the outcome (hazard ratio 4.0, 95% confidence interval 1.0-15.6, P = 0.046). CONCLUSION: In hypertensive patients at low/moderate CV risk, IDH and SDH phenotypes defined by clinic BP measurements, equally determined CV events but to a lower extent compared with ISH.

Talonavicular Dislocation-What Lies Beneath?

BACKGROUND: The talonavicular joint is a rare site of dislocation. Its etiology varies and can be the result of either acute trauma or a chronic degenerative process that most commonly occurs in patients with rheumatoid arthritis or Charcot arthropathy. Our aim is to highlight the relationship between the underlying pathology of talonavicular dislocations and the final outcome in the case of operative management. METHODS: We present three cases of talonavicular dislocation with the dislocation itself as the only common denominator, and a completely different etiology, natural history, treatment, and prognosis among them. RESULTS: There was one case of a traumatic talocalcaneonavicular dislocation in a healthy individual, one case in a rheumatoid arthritis patient, and one case in a patient with diabetes mellitus. All patients were treated surgically. The outcomes were excellent, fair, and poor, respectively. CONCLUSIONS: Among many factors that influence prognosis, it is equally critical to evaluate the overall background in which the dislocation occurs so as to apply the suitable treatment. The surgeon not only needs to treat the local incident but also appreciate the general medical condition to provide the best final outcome to the patient.

Where is the aorta? Is it worth palpating the aorta prior to laparoscopy?

BACKGROUND: Injury to major retroperitoneal vessels is the most catastrophic complication of laparoscopy. Knowledge of the site of the aortic bifurcation prior to inserting the umbilical port would be expected to reduce the risk of this type of injury. The aim of the study is to determine the feasibility of identifying the aortic bifurcation by palpation prior to the operation. METHODS: We studied 100 patients undergoing laparoscopic surgery or laparotomy. After prepping and draping, the operating surgeon felt for the aortic bifurcation to determine its position in relation to the umbilicus. We then related our findings to the height, weight, and body mass index of the patient. RESULTS: The aorta could not be palpated in 15% of cases, including almost 2/3 of women who were obese (body mass index >30). In the remaining 85% cases, where the aorta was palpable, the bifurcation was above the level of the umbilicus in 30 (35%) cases, at the umbilicus in 45 (53%) cases, and below in 10 (12%) cases. We did not find any significant effect of body mass index, height, or weight on the level of the aortic bifurcation by palpation. No vascular injury occurred in the laparoscopic cases during the study. CONCLUSIONS: The aortic bifurcation is palpable in the majority of women undergoing surgery, including 93% of those with a low or normal body mass index who are at higher risk of vascular injury. We recommend the routine palpation for the aortic bifurcation as a simple means to reduce the risk of injury to a major retroperitoneal vessel.
