ABSTRACT

Introduction: Heart failure (HF) presents a significant health challenge, with intravenous (IV) iron therapy considered a potential treatment avenue. Method: We assessed IV iron therapy's efficacy in HF patients with concurrent iron deficiency versus standard of care. Primary outcomes included the composite of HF hospitalizations or cardiovascular-related mortality, HF hospitalizations, and all-cause, HF, and cardiovascular mortality rates. Secondary measures encompassed improvements in New York Heart Association functional classification, quality of life, 6-minute walk test, left ventricular ejection fraction, and adverse events. We used a random-effects model to compute relative risk (RR) or mean difference (MD) with 95% confidence intervals (CIs). Results: Based on an analysis of 14 randomized controlled trials involving 6614 patients, IV iron therapy significantly reduced composite outcome (RR: 0.84, 95% CI: 0.73, 0.96; P = 0.01) and HF hospitalizations (RR: 0.74, 95% CI: 0.61, 0.89; P = 0.002) compared to standard of care. Mortality rates showed no significant difference. IV iron therapy improved New York Heart Association functional classification, quality of life, and 6-minute walk test, with no major impact on left ventricular ejection fraction. Adverse events remained stable. Conclusions: IV iron therapy holds promise for diminishing HF hospitalizations and enhancing quality of life and 6-minute walk test in HF patients. Yet, its effect on all-cause or cardiovascular mortalities appears limited.

ABSTRACT

An anomalous coronary artery (ACA) is a congenital malformation or variation where one or both coronary arteries have an abnormal origin. This condition has been associated with a high risk of adverse cardiac events, including sudden cardiac death. Our patient initially presented nine years before the diagnosis of the ACA with anginal chest pain on exertion. The patient had positive nuclear stress with both ST depressions and ST elevations, as well as transient ischemic dilatation of 1.36. A coronary artery angiogram revealed an anomalous left coronary artery originating from the right coronary sinus. The distal anatomy was determined with coronary computed tomography angiography (CCTA), which showed an interarterial course. The patient underwent coronary artery bypass surgery following CCTA.

ABSTRACT

Radial artery occlusion (RAO) is a well known complication that occurs after traditional radial artery (TRA) intervention and limits the radial artery as a future access site, as well as an arterial conduit. Distal radial artery (DRA) access has emerged recently as an alternative approach with a potential lower incidence of RAO. Database search of Pubmed/MEDLINE, Cochrane Library, and EMBASE was conducted by two authors from inception through 1 October 2022. Randomized trials that compared TRA with the DRA approach to perform coronary angiography were included. Two authors extracted pertinent data into predefined data collection tables. The risk ratios and 95% confidence intervals (CIs) were reported. Eleven trials were included (5700 patients) in the study. The mean age was 62.0 ±â€…10.9 years. Compared with DRA, vascular access through the TRA was associated with a higher incidence of RAO (risk ratio 3.05, 95% CI, 1.74-5.35, P < 0.01); however, arterial access by using the TRA was associated with a lower incidence of access failure leading to a crossover compared with the DRA approach (risk ratio 0.35; 95% CI, 0.21-0.57, P < 0.01). The incidence of radial artery spasm and access site-associated hematoma was not significant in the group treated with TRA compared with the DRA approach (P > 0.05). The DRA approach was associated with a lower incidence of RAO compared with the TRA approach but this was at the expense of a higher crossover rate.

ABSTRACT

INTRODUCTION: In the setting of acute ST-elevation myocardial infarction (STEMI), several randomized control trials (RCTs) suggested a potential benefit with the use of therapeutic hypothermia (TH). However, results from previous studies are contradictory. METHOD: We performed a comprehensive literature search for studies that evaluated the efficacy and safety of adjunctive TH compared to the standard percutaneous coronary intervention (PCI) in awake patients with STEMI. The primary outcomes were the infarct size (IS) and microvascular obstruction (MVO) assessed by cardiac imaging at the end of follow-up. The secondary outcomes were major adverse cardiovascular events (MACE), procedure-related complications, and door-to-balloon time. Relative risk (RR) or the mean difference (MD) and corresponding 95 % confidence intervals (CIs) were calculated using the random-effects model. RESULTS: A total of 10 RCTs, including 706 patients were included. As compared to standard PCI, TH was not associated with a statistically significant improvement in the IS (MD: -0.87 %, 95%CI: -2.97, 1.23; P = 0.42) or in the MVO (MD: 0.11 %, 95%CI: -0.06, 0.27; P = 0.21). MACE and its components were comparable between the two groups. However, the TH approach was associated with an increased risk of infection and prolonged door-to-balloon time. Furthermore, there was a trend in the TH group toward an increased incidence of stent thrombosis and paroxysmal atrial fibrillation. CONCLUSIONS: According to our meta-analysis of published RCTs, TH is not beneficial in awake patients with STEMI and has a marginal safety profile with potential for care delays. Larger-scale RCTs are needed to further clarify our results.

ABSTRACT

Deglutition syncope is a form of situational syncope where patients develop presyncope or syncope during swallowing. This condition has been observed to occur most commonly in patients with prior gastroesophageal conditions. Our patient developed deglutition syncope that started to occur a few weeks after undergoing a total thyroidectomy. The patient was found to have paroxysmal atrioventricular (AV) block, with up to 5.1 seconds of asystole during swallowing, manifested with episodes of dizziness and lightheadedness. A barium swallow test revealed normal peristalsis and no evidence of dysmotility. The patient underwent placement of a dual chamber pacemaker, and the syncopal episodes resolved. Interrogation of the pacemaker showed no recorded abnormal events.

ABSTRACT

PURPOSE OF REVIEW: To evaluate remote monitoring using implantable cardioverter-defibrillator (ICD) or cardiac resynchronization therapy defibrillator (CRT-D) devices as an adjunctive tool to the traditional care of patients with heart failure (HF). RECENT FINDINGS: We included 11 trials encompassing 5965 patients. Absolute risk difference (ARD) with 95% credible interval (CrI) was estimated. Pooled (posterior) risk difference was computed using Bayesian hierarchical methods. The ARD for mortality was centered at - 0.01 (95% CrI: - 0.03; 0.01, Tau: 0.02), with an 82% probability of ARD of ICD/CRT-D remote monitoring with respect to control being less than 0. The ARD for cardiovascular mortality was centered at - 0.03 (95% CrI: - 0.11; 0.05, Tau: 0.10), with an 84% probability of ARD of ICD/CRT-D remote monitoring with respect to control being less than 0. ICD/CRT-D remote monitoring in patients with HF is associated with a higher probability of reduced all-cause and cardiovascular mortality compared with standard care alone.

ABSTRACT

Limited data is available regarding the safety and effectiveness of drug-coated balloon (DCB) versus conventional percutaneous transluminal balloon angioplasty (PTA) in the treatment of critical limb ischemia because of infrapopliteal peripheral arterial disease. We conducted an updated meta-analysis to assess the safety and efficacy of DCB in the treatment of infrapopliteal disease. A database search of PubMed/MEDLINE, EMBASE, and the Cochrane Library was performed by 2 reviewers from inception through November 15, 2021. Randomized trials that compared DCB with conventional PTA in treating infrapopliteal arterial disease were included. The risk ratios (RRs) and 95% confidence intervals (CIs) were reported. A total of 9 trials were included (1,501 participants) in the study. The mean age was 71.1 ± 10.2 years. Regarding the primary end points, treating infrapopliteal arterial disease with DCB had a lower incidence of re-stenosis (RR 0.48, 95% CI 0.33 to 0.70, p = 0.0001) with no significant difference in all-cause mortality (RR 1.11, 95% CI 0.73 to 1.69, p = 0.61), compared with conventional PTA. With regards to the secondary end points, DCB usage was associated with a significant reduction in clinically driven target lesion revascularization (RR 0.54, 95% CI 0.35 to 0.84, p = 0.006) with no significant difference with regards to major target limb amputation and major adverse cardiovascular events (p ≥0.05). In conclusion, among patients with critical limb ischemia secondary to infrapopliteal artery disease, DCB usage was associated with a significantly lower number of restenosis and clinically driven target lesion revascularization compared with conventional PTA. There was no increase in all-cause mortality or major target limb amputation with the use of DCB.

ABSTRACT

Introduction: Catheter placement and stability are well-known challenges in atrial fibrillation (AF) ablation. As a result, steerable sheaths (SS) were developed to improve catheter stabilization and maintain proper catheter-tissue contact. The purpose of this systematic review and meta-analysis is to see if employing a SS influences procedure outcome. Method: We performed a comprehensive literature search for studies that evaluated the efficacy and safety of SS compared to nonsteerable sheaths (NSS) in AF ablation. The primary outcome was the rate of atrial arrhythmia (AA) freedom by the time of the last follow-up. The secondary outcomes were the procedure-related complications and procedural characteristics. Risk ratio (RR) or the mean difference (MD) and corresponding 95% confidence intervals (CIs) were calculated using the random-effects model. Results: A total of 10 studies, including 967 AF patients (mean age: 59.2 ± 11.1 years, 516 patients managed with SS vs. 454 with NSS), were included. SS group showed a higher rate of freedom of AA compared to NSS (RR: 1.19; 95% CI 1.09-1.29; p < .001). Both techniques had similar rate for procedural-related complication (RR: 1.09, 95% CI 0.50-2.39; p = .83). The SS strategy had a shorter procedure time (MD -10.6 [min], 95% CI -20.97, -0.20; p = .05) but comparable fluoroscopic and radiofrequency application times to the NSS group. Conclusions: The SS for AF catheter ablation not only reduced the total procedure time but also significantly increased the rate of successful ablation while maintaining a similar safety profile when compared to the traditional NSS.

ABSTRACT

Patients with cancer are at higher risk of atrial fibrillation (AF). Currently there are no definitive data on clinical outcomes for nonvitamin K antagonist oral anticoagulant (NOACs) and warfarin in cancer patients with AF. Therefore, we conducted a meta-analysis to evaluate the efficacy and safety of NOACs compared with warfarin. A search through Pubmed/MEDLINE, Embase, and Cochrane library was done from the databases inception to March 2022. Studies that compared NOACs to warfarin in the setting of AF and cancer were included. The primary outcomes were the incidence of major bleeding and ischemic stroke/systemic embolism (SE). Secondary outcomes were major adverse cardiovascular event (MACE), intracranial bleeding, and Major gastrointestinal bleeding. Risk ratios (RRs) with 95% confidence intervals (CI) were used to report the outcomes. A total of 11 studies were included. We found that NOACs were associated with a lower incidence of major bleeding and combined ischemic stroke/SE in patients with AF and cancer compared with warfarin (RR 0.57; 95% CI 0.44-0.75, P < 0.0001 and RR 0.59; 95% CI 0.47-0.75, P < 0.0001, respectively). Also, there was lower incidence of Intracranial and major gastrointestinal bleeding in patients who received NOACs compared with warfarin (P < 0.0001). Network analyses revealed that apixaban and dabigatran were associated with reduction of major bleeding compared with warfarin. Among patients who diagnosed with AF and cancer, NOACs were associated with lower incidence of major bleeding ischemic stroke/SE compared with warfarin. Furthermore, NOACs were associated with lower gastrointestinal and intracranial bleeding.

ABSTRACT

Patients with established atherosclerotic cardiovascular disease (ASCVD) need long-term antiplatelet therapy to decrease the risk of future ASCVD events. We searched PubMed, Cochrane Library, and ClinicalTrials.gov (inception through September 2021) for randomized controlled trials (RCTs) evaluating P2Y12 inhibitors vs aspirin for secondary prevention of ASCVD events. Seven RCTs including a total of 56,982 patients were included in this analysis. The median follow-up duration was 22.8 (IQR 12) months. When P2Y12 inhibitors were compared with aspirin as long-term antiplatelet therapy for secondary prevention of ASCVD events, there was a significant decrease in the risk of myocardial infarction [RR: 0.83; 95% CI: 0.72-0.94], and stroke [RR: 0.90; 95% CI: 0.83-0.99]. However, there was no significant difference in all-cause mortality [RR: 1.02; 95% CI: 0.92-1.12], or cardiovascular mortality [RR: 0.95; 95% CI: 0.83-1.08] between P2Y12 inhibitors and aspirin users. Additionally, there was no significant difference in major bleeding events [RR: 0.88; 95% CI: 0.74-1.04], or all bleeding events [RR: 1.09; 95% CI: 0.90-1.33] between P2Y12 inhibitors and aspirin groups. Use of P2Y12 inhibitor monotherapy is associated with lower rates of myocardial infarction and stroke in ASCVD patients without any significant difference in mortality, or bleeding compared to aspirin monotherapy.

ABSTRACT

Sodium-glucose cotransporter 2 (SGLT2) inhibitors reduce cardiovascular events and renal outcomes in patients with diabetes mellitus (DM). This meta-analysis aimed to provide a thorough evaluation regarding the efficacy and safety of SGLT2 inhibitors. Data search of MEDLINE/PubMed, Embase, and Cochrane Library databases and ClinicalTrials.com from inception through November 26, 2020. We included randomized trials, SGLT2 inhibitors compared with placebo, patients with or without diabetes at recruitment, and reporting the incidence of cardiovascular or renal outcomes. Two authors extracted pertinent data into predefined data collection tables. Ten trials were included (71,553 patients). The mean age was 64.7 ± 8.4 years, with 65.1% male. Follow-up durations range 9-50 months. Inhibition of SGLT2 resulted in lower composite outcome of heart failure (HF) hospitalization or cardiovascular death (RR 0.76, 95% CI 0.73-0.81, P < 0.01) and lower risk of renal outcomes (RR 0.68, 95% CI 0.60-0.77, P < 0.01). Furthermore, SGLT2 inhibitors were associated with lower major adverse cardiovascular events (MACEs), HF hospitalization, cardiovascular mortality, all-cause mortality, myocardial infarction, and serious adverse events, compared with placebo (P < 0.05). Sensitivity analyses revealed lower MACE events also in patients with HF, and a lower HF hospitalization and cardiovascular mortality in non-diabetic patients (P < 0.05). While the amputation risk was comparable between the two groups, the risk of diabetic ketoacidosis was higher in the SGLT2 inhibitor group. Inhibition of SGLT2 in patients with DM and prevalent ASCVD reduces the risk of HF hospitalization, cardiovascular mortality, all-cause mortality, MACE, and renal outcomes without increasing the risk of serious adverse events or amputation.

ABSTRACT

Previous studies have reported contradictory findings on the utility of remote physiological monitoring (RPM)-guided management of patients with chronic heart failure (HF). Multiple databases were searched for studies that evaluated the clinical efficacy of RPM-guided management versus standard of care (SOC) for HF patients. The primary outcome was HF-related hospitalization (HFH). The secondary outcomes were all-cause mortality, cardiovascular-related (CV) mortality, and emergency department (ED) visits. Pooled relative risk (RR) and corresponding 95% confidence intervals (CIs) were calculated and combined using a random-effects model. A total of 16 randomized controlled trials, including 8679 HF patients (4574 managed with RPM-guided therapy vs. 4105 managed with SOC), were included in the final analysis. The average follow-up period was 15.2 months. There was no significant difference in HFH rate between the two groups (RR: 0.94; 95% CI: 0.84-1.07; P = 0.36). Similarly, there were no significant differences in CV mortality (RR 0.86, 95% CI 0.73-1.02, P = 0.08) or in ED visits (RR 0.80, 95% CI 0.59-1.08, P = 0.14). However, RPM-guided therapy was associated with a borderline statistically significant reduction in all-cause mortality (RR: 0.88; 95% CI: 0.78-1.00; P = 0.05). Subgroup analysis based on the strategy of RPM showed that both hemodynamic and arrhythmia telemonitoring-guided management can reduce the risk of HFH (RR: 0.79; 95% CI: 0.64-0.97; P = 0.02) and (RR: 0.79; 95% CI: 0.67-0.94; P = 0.008) respectively. Our study demonstrated that RPM-guided diuretic therapy of HF patients did not reduce the risk of HFH but can improve survival. Hemodynamic and arrhythmia telemonitoring-guided management could reduce the risk of HF-related hospitalizations.

ABSTRACT

INTRODUCTION: Distal transradial artery access (DTRA) has recently gained attention due to potential benefits in terms of local complications. In this meta-analysis, we aimed to evaluate the utility of DTRA compared to conventional transradial artery access (CTRA) for coronary angiography and intervention. METHOD: Multiple databases were searched from inception through May 2021 for all the studies that evaluated the efficacy and safety of DTRA in the coronary field. The primary outcome was the access success rate. The secondary outcomes were periprocedural local complications (site hematoma, radial artery occlusion, and spasm) and procedural characteristics (cannulation, fluoroscopy, procedure, and radial artery compression times). All meta-analyses were conducted using a random-effect model. RESULTS: A total of 12 studies (including four randomized control trials) with 1634 patients who underwent DTRA vs. 1657 with CTRA were included in the final analysis. The access success rate was similar between the two groups (odds ratio (OR):0.62; 95% confidence interval (CI):0.30-1.26; P = 0.18; I2 = 61%). DTRA was associated with a statistically significant lower rate of radial artery occlusion (OR:0.36; 95% CI: 0.22-0.59; P < 0.001; I2 = 0%) but similar rates of radial artery spasm and site hematoma when compared to CTRA. Regarding the procedural characteristics, despite having a longer canulation time (mean difference (min.) [MD] 0.89, 95% CI 0.36-1.42; P < 0.0001), DTRA was associated with shorter compression time and comparable fluoroscopy and procedure times. CONCLUSIONS: Our meta-analysis demonstrates that the DTRA is effective and safe with superiority in preventing radial artery occlusion when compared to CTRA.

ABSTRACT

PURPOSE: To evaluate the efficacy and safety of midodrine use in intensive care units (ICU) to facilitate weaning off intravenous vasopressors (IVV). METHODS: We searched PubMed/MEDLINE, Cochrane library, and Google Scholar (inception through October 18th, 2020) for studies evaluating adjuvant use of midodrine to IVV in the ICU. The outcomes of interest were ICU length of stay (LOS), hospital LOS, mortality, IVV reinstitution, ICU readmission, and bradycardia. Estimates were pooled using the random-effects model. We reported effect sizes as standardized mean difference (SMD) for continuous outcomes and risk ratios (RRs) for other outcomes with a 95% confidence interval (CI). RESULTS: A total of 6 studies were found that met inclusion criteria and had sufficient data for our quantitative analysis (1 randomized controlled trial and 5 retrospective studies). A total of 2,857 patients were included: 600 in the midodrine group and 2,257 patients in the control group. Midodrine use was not associated with a significant difference in ICU LOS (SMD 0.16 days; 95% CI -0.23 to 0.55), hospital LOS (SMD 0.03 days; 95% CI -0.33 to 0.0.39), mortality (RR 0.87; 95% CI 0.52 to 1.46), IVV reinstitution (RR 0.47; 95% CI 0.17 to 1.3), or ICU readmission (RR 1.03; 95% CI 0.71 to 1.49) when compared to using only IVV. However, there were higher trends of bradycardia with midodrine use that did not reach significance (RR 7.64; 95% CI 0.23 to 256.42). CONCLUSION: This meta-analysis suggests that midodrine was not associated with a significant decrease in ICU LOS, hospital LOS, mortality, or ICU readmissions.

ABSTRACT

Heart failure (HF) remains a leading cause of hospitalization and mortality. Marine omega-3 fatty acid supplements (omega-3 s) have shown efficacy in decreasing sudden cardiac death and improving the left ventricle ejection fraction percent (LVEF%). In this review, we evaluated the effect of marine omega-3 fatty acid supplements (omega-3 s) on HF hospitalization, recurrent HF hospitalization, and cardiovascular mortality in patients with heart failure. We found that omega-3 supplementation did not reduce first HF hospitalization or cardiovascular mortality but did significantly reduce recurrent HF hospitalizations, as compared with placebo.

ABSTRACT

GOALS AND BACKGROUND: Studies analyzing artificial intelligence (AI) in colonoscopies have reported improvements in detecting colorectal cancer (CRC) lesions, however its utility in the realworld remains limited. In this systematic review and meta-analysis, we evaluate the efficacy of AI-assisted colonoscopies against routine colonoscopy (RC). STUDY: We performed an extensive search of major databases (through January 2021) for randomized controlled trials (RCTs) reporting adenoma and polyp detection rates. Odds ratio (OR) and standardized mean differences (SMD) with 95% confidence intervals (CIs) were reported. Additionally, trial sequential analysis (TSA) was performed to guard against errors. RESULTS: Six RCTs were included (4996 participants). The mean age (SD) was 51.99 (4.43) years, and 49% were females. Detection rates favored AI over RC for adenomas (OR 1.77; 95% CI: 1.570-2.08) and polyps (OR 1.91; 95% CI: 1.68-2.16). Secondary outcomes including mean number of adenomas (SMD 0.23; 95% CI: 0.18-0.29) and polyps (SMD 0.23; 95% CI: 0.17-0.29) detected per procedure favored AI. However, RC outperformed AI in detecting pedunculated polyps. Withdrawal times (WTs) favored AI when biopsies were included, while WTs without biopsies, cecal intubation times, and bowel preparation adequacy were similar. CONCLUSIONS: Colonoscopies equipped with AI detection algorithms could significantly detect previously missed adenomas and polyps while retaining the ability to self-assess and improve periodically. More effective clearance of diminutive adenomas may allow lengthening in surveillance intervals, reducing the burden of surveillance colonoscopies, and increasing its accessibility to those at higher risk. TSA ruled out the risk for false-positive results and confirmed a sufficient sample size to detect the observed effect. Currently, these findings suggest that AI-assisted colonoscopy can serve as a useful proxy to address critical gaps in CRC identification.

ABSTRACT

INTRODUCTION: There is a persistent controversy regarding the benefit and timing of angiography in patients with stable coronary artery disease (CAD). With this meta-analysis of randomized controlled trials (RCTs) the advantages of initial invasive strategy and medical therapy compared with only medical therapy. METHODS: We conducted a literature search of the following databases Pubmed/MEDLINE, Cochrane Library and Embase. Data was collected from all the RCTs that compared early invasive approach with medical therapy alone in treating stable CAD which was conducted by two independent authors. Primary outcomes were all-cause mortality and myocardial infarction (MI), while the secondary outcomes included major adverse cardiovascular events (MACE), cardiovascular mortality, cardiovascular hospitalization, hospitalization due to unstable angina and revascularization events. The Mantel-Haenszel random-effects model was used to estimate risk ratios (RRs) and 95% confidence intervals (CIs). RESULTS: We included 15 RCTs (13 916 patients, mean age 63.1, 78.9% men). The early invasive strategy, compared with medical therapy alone, did not reveal a significant reduction in the incidence of all-cause mortality (RR, 0.94; 95% CI, 0.84-1.05, P = 0.30) or MI (RR, 0.93; 95% CI, 0.79-1.10, P = 0.42). Furthermore, the early invasive strategy did not reduce the incidence of cardiovascular mortality, cardiovascular hospitalization or the revascularization rate compared with medical therapy alone (P > 0.05). However, the incidence of MACE and hospitalization due to unstable angina were lower in patients treated with early invasive strategy (RR, 0.79; 95% CI, 0.63-0.99, P = 0.04), and (RR, 0.46; 95% CI, 0.32-0.67, P < 0.0001), respectively. CONCLUSIONS: Early invasive strategy with medical therapy did not reduce the incidence of all-cause mortality and MI when compared with medical therapy alone among patients with stable CAD with significant stenosis. However, there was a significant reduction in the incidence of MACE and hospitalization due to unstable angina in the early invasive group.
