Reduction of cardiovascular complications during delivery hospitalization in patients undergoing bariatric procedures.

BACKGROUND: The global surge in obesity presents a significant health challenge, leading to increased adoption of bariatric surgery as an intervention. However, the correlation between bariatric surgery and cardiovascular outcomes during subsequent pregnancies remains unclear. The aim of our study was to determine the prevalence of cardiovascular complications during delivery hospitalizations in patients with bariatric procedure. METHODS: We performed a retrospective analysis utilizing the National Inpatient Sample database to examine data from delivery admissions of pregnant women with obesity and a history of bariatric surgery. These admissions were identified using International Classification of Diseases (ICD) codes from 2009 to 2019. In comparing pregnant individuals who had undergone bariatric surgery with those with obesity but had no such surgical history, we assessed the prevalence of cardiovascular complications. RESULTS: Our study included 3,027,987 pregnancies in individuals with obesity and an additional 117,350 pregnancies following bariatric surgery. Compared to patients without bariatric surgery, post-surgery patients were older (32.84 years vs 29.02 years), primarily White (59.0%), and mostly treated in large urban hospitals. Cardiovascular outcomes showcased reduced odds of congestive heart failure [Adjusted odds ratios (AOR) 0.11, 95% confidence intervals (CI) 0.01-0.74], gestational hypertensive complications (AOR 0.55, 95% CI 0.53-0.59), and cardiac arrhythmia (AOR 0.76, 95% CI 0.64-0.89) in the post-surgery group, with no significant difference in peripartum cardiomyopathy rates (AOR 0.72, 95% CI 0.29-1.76) and no instances of stroke or acute MI. Perinatally, the surgery cohort had higher odds of preterm birth (AOR 1.30, 95% CI 1.24-1.38) and fetal growth restriction (AOR 2.47, 95% CI 2.32-2.63) but fewer incidents of being large for gestational-age (AOR 0.35, 95% CI 0.32-0.38). As bariatric surgery became increasingly recognized as a significant factor in certain complications, its prevalence among the study population increased from 2009 to 2019. CONCLUSION: In summary, our research indicates that bariatric surgery is associated with a decreased risk of cardiovascular complications during delivery. This study highlights how insights from bariatric surgery outcomes could shape clinical guidelines for managing obesity in pregnant women.

ST segment elevation in an adult chest pain patient: A case of coronary artery vasospasm.

Chest pain is one of the most common symptoms of patients presenting to the emergency department (ED) in the United States, accounting for up to eight million cases annually. We present a 55-year-old male who was brought in to the ED with sudden onset chest pain and was found to have ST-segment elevations in the infero-lateral leads on electrocardiogram (ECG). These changes resolved with nitroglycerin. Coronary artery vasospasm was diagnosed as coronary angiogram was normal. Calcium channel blocker was prescribed with good symptom relief. The most important teaching point is, coronary vasospasm as a cause of ST-segment elevation is missed frequently and should be considered among the differentials in patients presenting with chest pain. Nitrates and/or calcium channel blockers along with avoidance of triggers can help in symptom management.

Speckle tracking echocardiography can predict subclinical myocardial involvement in patients with sarcoidosis: A meta-analysis.

BACKGROUND: This meta-analysis aims to evaluate the utility of speckle tracking echocardiography (STE) as a tool to evaluate for cardiac sarcoidosis (CS) early in its course. Electrocardiography and echocardiography have limited sensitivity in this role, while advanced imaging modalities such as cardiac magnetic resonance (CMR) and 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) are limited by cost and availability. METHODS: We compiled English language articles that reported left ventricular global longitudinal strain (LVGLS) or global circumferential strain (GCS) in patients with confirmed extra-cardiac sarcoidosis versus healthy controls. Studies that exclusively included patients with probable or definite CS were excluded. Continuous data were pooled as a standard mean difference (SMD), comparing sarcoidosis group with healthy controls. A random-effect model was adopted in all analyses. Heterogeneity was assessed using Q and I2 statistics. RESULTS: Nine studies were included in our final analysis with an aggregate of 967 patients. LVGLS was significantly lower in the extra-cardiac sarcoidosis group as compared with controls, SMD -3.98, 95% confidence interval (CI): -5.32, -2.64, P < .001, also was significantly lower in patients who suffered major cardiac events (MCE), -3.89, 95% CI -6.14, -1.64, P < .001. GCS was significantly lower in the extra-cardiac sarcoidosis group as compared with controls, SMD: -3.33, 95% CI -4.71, -1.95, P < .001. CONCLUSION: LVGLS and GCS were significantly lower in extra-cardiac sarcoidosis patients despite not exhibiting any cardiac symptoms. LVGLS correlates with MCEs in CS. Further studies are required to investigate the role of STE in the early screening of CS.

Short duration of dual antiplatelet therapy following complex percutaneous coronary intervention: A systematic review and meta-analysis.

INTRODUCTION AND AIM: The optimal composition and duration of antiplatelet therapy after complex percutaneous coronary intervention (PCI) remains unclear. We conducted a meta-analysis to compare 1-3 months of dual antiplatelet therapy (DAPT) followed by monotherapy vs. 12 months of DAPT. METHOD: MEDLINE/PubMed, EMBASE, and Cochrane Central Register of Controlled Trials were queried for studies comparing 1-3 months of DAPT followed by monotherapy vs. 12 months of DAPT in the outcomes of complex PCI from inception through January 2023. Outcomes of interest included major bleeding, all-cause mortality, cardiovascular mortality, myocardial infarction (MI), stent thrombosis, target vessel revascularization, and stroke. RESULTS: Compared to 12 months, 1-3 months of dual antiplatelet therapy had a weak association with less major bleeding (OR 0.67; 95 % CI, 0.44-1.00; p = 0.05; I2 = 28 %). There were no significant differences between the shorter and longer antiplatelet therapy in terms of all-cause mortality (OR 0.83; 95 % CI, 0.59-1.16; p = 0.21; I2 = 17 %), cardiovascular mortality (OR 0.87; 95 % CI, 0.53-0.42; p = 0.50; I2 = 0), MI (OR 0.97; 95 % CI, 0.69-1.35; p = 0.82; I2 = 32 %), stent thrombosis (OR 1.17, 95 % CI, 0.77-1.76; p = 0.38; I2 = 0 %), target vessel revascularization (OR 1.05, 95 % CI, 0.58-1.89; p = 0.82; I2 = 64 %), or stroke (OR 1.10, 95 % CI, 0.55-2.17; p = 0.37; I2 = 7 %);. CONCLUSION: Among patients undergoing complex PCI, DAPT for 1-3 months may be associated with less major bleeding but similar rates of cardiovascular events (death, MI, stroke, stent thrombosis, and revascularization) compared to DAPT for 12 months.

Cardiac Arrest Secondary to Inferior ST-Segment-Elevation Myocardial Infarction in Patient with Paroxysmal Nocturnal Hemoglobinuria and COVID-19 Infection.

Patients with paroxysmal nocturnal hemoglobinuria (PNH) have transient attacks of complement-mediated hemolysis and thrombosis that can be spontaneous or secondary to precipitating factors such as infections. We present a case of a 63-year-old male patient with a medical history of PNH who presented with typical chest pain, fever, cough, jaundice, and dark-colored urine. On examination, he was hemodynamically stable but had conjunctival icterus. A few minutes after presentation, the patient suffered a ventricular fibrillation cardiac arrest and then achieved a return of spontaneous circulation after receiving two defibrillator shocks. EKG showed inferior wall ST-segment elevation myocardial infarction. Labs showed hemoglobin of 6.4 g/dl, elevated cardiac markers, serum lactate dehydrogenase, and indirect bilirubin. Serum haptoglobin was < 1 mg/dl. His COVID-19 polymerase chain reaction test was positive. Immediately, the patient received 2 units of packed RBCs and underwent a coronary angiogram (CA), which revealed total proximal occlusion of the right coronary artery. He underwent successful percutaneous coronary intervention (PCI), and two drug-eluting stents were placed. His peripheral blood immunophenotyping and flow cytometry showed loss of glycosylphosphatidylinositol-linked antigens and decreased expression of CD 59/14/24. He was started on ravulizumab, a humanized monoclonal antibody complement five inhibitor. Both PNH and COVID-19 increase the risk of thrombosis. Endothelial injury and cytokine storm increase the risk of thrombosis in COVID-19 patients, whereas the activation of the coagulation system and the impairment of the fibrinolytic system by complement cascade leads to thrombosis in PNH patients. Regardless of which pathway leads to coronary artery thrombosis, CA and PCI can be life-saving.

Delayed vs early cardioversion in patients with paroxysmal atrial fibrillation: a population-based study (2015-2020).

Aim: There is limited data on clinical outcomes of delayed cardioversion (DCV) compared with early cardioversion (ECV) in paroxysmal atrial fibrillation (AF) patients. Methods: We utilized data from National Inpatient Sample (2015-2020) and propensity-score matched analysis to determine adjusted odds ratio (aOR) of major clinical outcomes, including 17,879 AF cases: 9725 and 8154 underwent ECV and DCV, respectively. Results: Compared with ECV, DCV was associated with higher odds of acute heart failure (AHF; aOR 1.79 [1.67-1.92]; p < 0.01), median length of stay (4 vs 2 days; p < 0.01) and cost of hospitalization ($33,410 vs $21,738; p < 0.01) with no significant difference in inpatient mortality and other cardiovascular and neurological outcomes. Conclusion: Compared with ECV, DCV was associated with more AHF and resource utilization.

Long-term Outcomes of Acute Myocardial Infarction in Pre-existing Coronary Artery Ectasia: A Systematic Review and Meta-Analysis.

Coronary artery ectasia is associated with an increased risk of acute myocardial infarction. This meta-analysis evaluates outcomes following acute myocardial infarction in patients with pre-existing coronary artery ectasia. A search strategy was designed to utilize PubMed/Medline, EMBASE, and Google scholar for studies including the outcomes of acute myocardial infarction in patients with coronary artery ectasia from inception to February 10, 2022. We reported effect sizes as odds ratio (OR) with a 95% confidence interval (CI). We used I2 statistics to estimate the extent of unexplained statistical heterogeneity. There were 7 studies comprising 13,499 patients in the final analysis. There was no significant difference between patients with coronary ectasia and patients without coronary ectasia in terms of all-cause mortality (OR 0.95; 95% CI 0.58 to 1.56; P = 0.79; I2 = 0%), major adverse cardiovascular events (MACE; OR 4.04; 95% CI 0.34 to 47.57; P = 0.17; I2 = 95%), myocardial re-infarction (OR 2.13; 95% CI 0.83 to 5.47; P = 0.08; I2 = 59%), target vessel revascularization (OR 1.31; 95% CI 0.69 to 2.48; P = 0.21; I2 = 0%), or requiring mechanical supportive devices (OR 1.32; 95% CI 0.22 to 7.83; P = 0.57; I2 = 56%). Acute myocardial infarction in the presence of coronary artery ectasia is not associated with an increased risk of death, MACE, myocardial infarction, or the need for mechanical circulatory support.

Meta-Analysis of the Outcomes of Peri-Device Leak After Left Atrial Appendage Closure.

Left atrial appendage closure (LAAC) reduces the risk of thromboembolic stroke in atrial fibrillation. Peri-device leak (PDL) after LAAC may affect the subsequent risk of thromboembolism. We conducted a systematic review and meta-analysis to evaluate the effect of PDL after LAAC. We searched PubMed/Medline, Embase, and Google Scholar for studies reporting outcomes of PDL after LAAC from inception through October 2022. The primary outcome was the composite of stroke, transient ischemic attack (TIA), or systemic embolism (SE). Secondary outcomes included all-cause and cardiovascular mortality, ischemic stroke, TIA, and device-related thrombus. Outcomes were pooled using random-effects models. We used I2 statistics to assess statistical heterogeneity; I2 >50% considered significant heterogeneity. This study included 54,279 patients from 11 studies (6 observational, 2 nonrandomized controlled trials [non-RCTs] primary results, 2 RCT post hoc analyses, and 1 analysis combining 2 RCTs data). PDL was associated with a significant increase in the composite outcome of stroke, TIA, or SE (odds ratio 1.63, 95% confidence interval 1.06 to 2.52, p = 0.03, I2 = 43%) as compared with cases with no PDL. There were no significant differences in all-cause or cardiovascular mortality, ischemic stroke, TIA, or device-related thrombus. In conclusion, PDL after LAAC is associated with an increased risk of thromboembolism (composite stroke, TIA, or SE) without impacting mortality.

Gender Differences in International Cardiology Guideline Authorship: A Comparison of the US, Canadian, and European Cardiology Guidelines From 2006 to 2020.

Background Women continue to be underrepresented in cardiology and even more so in leadership positions. We evaluated the trends and gender differences in the guideline writing groups of the American College of Cardiology/American Heart Association (ACC/AHA), Canadian Cardiovascular Society (CCS), and European Society of Cardiology (ESC) guidelines from 2006 to 2020. Methods and Results We extracted all guidelines authors from 2006 to 2020, assessed their gender from publicly available profiles, and compared differences based on subspecialties and specific societies. Stratified and trend analyses were performed using χ2 and average annual percentage change/average 5 year percentage change. A total of 80 ACC/AHA (1288 authors [28% women]), 64 CCS (988 authors [26% women]), and 59 ESC (1157 authors [16% women]) guidelines were analyzed. A significant increase in inclusion of women was seen in ACC/AHA (12.6% [2006] to 42.6% [2020]; average annual percentage change, 6.6% [2.3% to 11.1%]; P=0.005) and ESC (7.1% [2006] to 25.8% [2020]; average annual percentage change, 6.6% [0.2% to 13.5%]; P=0.04), but the trend remained similar in CCS (20.6% [2006] to 36.3% [2020]; average annual percentage change, -0.1% (-3.7% to 3.5%); P=0.94), guideline authors. More women were coauthors in the ACC/AHA and ESC guidelines when women were chairs of guidelines. There was a persistent disparity of women among guideline authors for general cardiology and all subspecialties, except for pediatric cardiology and heart failure guidelines. The appointment of women authors as a chair was significantly low in all societies (22.4% [ACC/AHA], 16.9% [CCS], and 7.2% [ESC]; P=0.008). Conclusions There is a significant disparity in the inclusion of women on all national guideline committees, in addition to serving as a chair of cardiology guidelines. Further advocacy is required to promote equity, diversity, and inclusion in our cardiology guidelines globally.
