Sex difference in outcomes and management of cardiogenic shock: A systematic review and meta-analysis.

BACKGROUND: Cardiogenic shock (CS) is associated with significant morbidity and mortality. Sex differences in the outcomes and management of cardiogenic shock are not well established. The primary objective of this study is to investigate the differences inik cardiogenic shock outcomes between males and females. METHODS: A systematic review and meta-analysis were conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology. Studies were searched via the MEDLINE/PubMed, EMBASE, and Cochrane Central Register of Controlled Trials databases from inception to December 2022. RESULTS: The analysis included 24 studies comprising 1,567,660 patients. Compared to females, males with CS had a significantly lower risk of in-hospital all-cause mortality (risk ratio [RR] 0.88, 95 % confidence interval [CI] 0.85-0.90, p < 0.001) and 1-year mortality (RR 0.90, 95 % CI 0.89-0.92, p < 0.001). Males were more likely to undergo percutaneous coronary intervention (RR 1.21, 95 % CI 1.13-1.31, p < 0.0001) and intra-aortic balloon pump placement (RR 1.21, 95 % CI 1.11-1.32, p < 0.0001), with no significant sex differences in the use of extracorporeal membrane oxygenation or Impella. During the index hospitalization, males were at higher risk of arrhythmias (RR 1.18, 95 % CI 1.05-1.34, p = 0.003) and less likely to develop acute kidney injury (RR 0.86, 95 % CI 0.79-0.94, p < 0.001). CONCLUSION: Men have a lower all-cause mortality risk in cardiogenic shock. Addressing disparities in management is crucial for improving CS outcomes, especially for women.

Anterior STEMI in a 25-year-old with Cogan syndrome.

Cogan syndrome (CS) is a chronic inflammatory disorder primarily affecting young adults. It is characterized by interstitial keratitis, vestibuloauditory dysfunction, and, rarely, systemic vasculitis and aortitis. In this case report, we present a rare instance of a young male with anterior ST-elevation myocardial infarction in the context of aneurysmal coronary vessels and proximal occlusion of the left anterior descending artery. This case underscores the importance of recognizing cardiac risk factors in the setting of CS, as they can be life-threatening. Regular follow up is necessary, especially for patients showing signs of vasculitis or experiencing cardiac symptoms. A multidisciplinary approach to management can help optimize the prognosis for these complex patients. Learning objective: Comprehend Cogan syndrome (CS): Grasp the clinical manifestations and potential cardiovascular complications of CS. Diagnostic approach in CS: Differentiate cardiac symptoms in CS from typical coronary diseases, emphasizing the role of heart catheterization. Multidisciplinary management: Recognize the importance of integrating rheumatologists, cardiologists, and surgeons for optimal CS patient outcomes.

Percutaneous Intervention of LVAD Outflow Graft Obstruction and Thrombosis.

Left ventricular assist devices serve as a salvage therapy for patients with advanced heart failure. Complications such as thrombosis and obstruction can lead to acute device malfunction, posing significant clinical risks. A multidisciplinary approach is crucial for management. Few cases in the literature have demonstrated the safety and efficacy of percutaneous intervention, which holds significant value due to its less invasive nature and minimal risk of morbidity, especially in high-risk surgical patients.

Outcomes and Readmissions after Left Atrial Appendage Occlusion in Octogenarians: A Contemporary Analysis.

INTRODUCTION AND OBJECTIVES: The outcomes of left atrial appendage occlusion (LAAO) with the Watchman device in octogenarians are unknown as this population was underrepresented in major clinical trials. This study aims at examining the causes and outcomes of readmission after LAAO. DESIGN: A retrospective cohort study based on the National Readmission Database in the United States. SETTINGS AND PARTICIPANT: Patients aged ≥80 years, admitted between January 2016 and December 2018, with the primary diagnosis of atrial fibrillation or flutter or who had LAAO were included in the study. Patients who died during index admission were excluded. METHODS: We used the National Readmission Database and International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes to identify study participants. Data analysis was performed through Stata, version 17. Univariate and multivariate aggression analysis was used to adjust for confounders using Student t tests and χ2 tests. RESULTS: We identified 491,329 patients on anticoagulation (AC) and 2030 patients who underwent LAA closure. Neither group differed regarding hypertension, previous myocardial infarction, or valvular heart disease. All-cause readmissions were lower in the LAAO group at 45 days (adjusted P < .01). All-cause readmissions at 45 and 90 days were similar in both groups. There was an increase in gastrointestinal bleeding (GIB) readmissions in the LAAO at 45 (P < .01), 90 (P < .01), and 180 (P < .01) days. There was no difference in GIB readmission between the 2 groups. There was no also difference in stroke or intracranial hemorrhage rates between the 2 groups throughout the follow-up period. CONCLUSION AND IMPLICATIONS: In octogenarians who received LAAO, the rate of GIB increased during the first 6 months after the procedure; however, it was not different from that of AC after that. Special attention should be given to the antithrombotic regimens after LAAO to avoid bleeding in this vulnerable patient population.

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.

Safety and Efficacy of Cangrelor in Acute Coronary Syndromes: A Systematic Review and Network Meta-Analysis.

INTRODUCTION: Cangrelor is a potent intravenous non-thienopyridine P2Y12 inhibitor. We conducted a network meta-analysis to study the efficacy and safety of cangrelor as compared with the oral P2Y12 inhibition, clopidogrel, or placebo in acute coronary syndromes. METHODS: This meta-analysis followed the Cochrane collaboration guidelines and the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) protocols. Outcomes of interest included all-cause mortality, myocardial infarction, stent thrombosis, target vessel revascularization, major bleeding, minor bleeding, and the need for blood transfusion. RESULTS: The analysis was comprised of 6 studies including 26,444 patients treated with cangrelor, clopidogrel, or placebo. There were no statistically significant differences in the incidence of all-cause mortality, myocardial infarction, stent thrombosis, target vessel revascularization, or major bleeding. Cangrelor was associated with a higher risk of minor bleeding than clopidogrel or placebo, with no difference in requiring blood transfusion. CONCLUSION: Cangrelor has comparable outcomes to clopidogrel in patients with acute coronary syndromes and can be used as a reliable alternative in this population.

Successful Management of Severe Bupropion Toxicity with Lipid Emulsion Therapy: A Complex Case Report and Literature Review.

This case report presents the management of a 53-year-old female with a complex psychiatric history who ingested multiple medications, resulting in severe cardiovascular compromise and subsequent respiratory failure. The patient's ingestion included clonidine, fluoxetine, gabapentin, quetiapine and bupropion. Initial treatment involved supportive measures, including fluid resuscitation, bicarbonate infusion and correction of electrolyte imbalances. Despite these interventions, the patient remained haemodynamically unstable, requiring multiple vasopressors. Lipid emulsion therapy was initiated and led to a remarkable improvement in the patient's cardiovascular status. However, she developed acute respiratory distress syndrome (ARDS) and required prolonged mechanical ventilation. Steroid therapy was initiated to manage the ARDS, and the patient was successfully extubated on day 6. The case highlights the potential effectiveness of lipid emulsion therapy in managing bupropion toxicity, but emphasises the need for further research to establish clear guidelines on dosing, timing and safety protocols. Adverse effects associated with lipid emulsion therapy must be carefully considered. Individualised decision-making and patient-centred care is crucial in optimising outcomes in cases of bupropion toxicity. LEARNING POINTS: Recognise the cardiotoxic effects of bupropion toxicity: be vigilant in identifying cardiotoxic effects such as prolonged QTc, hypotension and arrhythmias in cases of bupropion toxicity.Consideration of intravenous lipid emulsion therapy for toxic injections of lipophilic drugs such as bupropion: in severe lipophilic drug ingestions, such as bupropion, consider using intravenous lipid emulsion therapy as a potential treatment option.Individualised decision-making and monitoring is necessary when using lipid emulsion therapy: tailor treatment based on the patient's condition and closely monitor for responses and potential adverse effects when using lipid emulsion therapy.

Efficacy and safety of the new generation Watchman FLX device compared to the Watchman 2.5: a systematic review and meta-analysis.

INTRODUCTION: The first-generation Watchman 2.5 (W 2.5)TM presented several limitations, such as challenges in implantation within complex left atrial appendage (LAA) anatomies, higher incidence of peri-device leak, device recapture, and device-related thrombus (DRT). The newer generation Watchman FLX (W-FLX)TM was introduced with a modified design aiming to overcome these limitations. The purpose of this meta-analysis is to conduct a comparative assessment of the safety and efficacy of the W-FLX and 2.5 devices in clinical practice. METHOD: The meta-analysis was conducted according to the preferred reporting items for systematic review and meta-analysis protocols (PRISMA). Studies were located through a search strategy utilizing PubMed, Cochrane, Google scholar and MEDLINE from inception to March 2023, with a primary objective to compare the safety and efficacy of the W-FLX and W 2.5 devices. After applying the selection criteria, five studies were included in this analysis. RESULTS: The analysis included five studies comprising 54,727 patients. The W-FLX is associated with an increase in procedural success (OR 7.49 [95% CI 1.98-28.26, P = 0.02; I2 = 0%]), and a significant reduction in mortality (OR 0.52 [95% CI 0.51-0.54, P<0.01; I2 = 0%], major bleeding 0.57 [95% CI 0.51-0.64, P<0.01; I2 = 0%]), device embolism (OR 0.35 [95% CI 0.18-0.70, P = 0.02; I2 = 0%]), and pericardial effusion (OR 0.33 [95% CI 0.26-0.41, P<0.01; I2 = 0%]). The rates of DRT and stroke were similar between the two groups. CONCLUSION: Compared to the W 2.5, the W-FLX was associated with a higher procedural success rate and significantly reduced adverse outcomes including mortality, major bleeding, device embolization, and pericardial effusion.

Trends in Colorectal Cancer Mortality in the United States, 1999 - 2020.

Background: The United States faces a significant public health issue with colorectal cancer (CRC), which remains the third leading cause of cancer-related fatalities despite early diagnosis and treatment progress. Methods: This investigation utilized death certificate data from the Centers for Disease Control and Prevention Wide-Ranging OnLine Data for Epidemiologic Research (CDC WONDER) database to investigate trends in CRC mortality and location of death from 1999 to 2020. Additionally, the study utilized the annual percent change (APC) to estimate the average annual rate of change over the specific time period for the given health outcome. Incorporating the location of death in this study served the purpose of identifying patterns related to CRC and offering valuable insights into the specific locations where deaths occurred. Results: Between 1999 and 2020, there were 1,166,158 CRC-related deaths. The age-adjusted mortality rates (AAMRs) for CRC consistently declined from 20.7 in 1999 to 12.5 in 2020. Men had higher AAMR (18.8) than women (13.4) throughout the study. Black or African American patients had the highest AAMR (21.1), followed by White (15.4), Hispanic/Latino (11.8), American Indian or Alaska native (11.4), and Asian or Pacific Islanders (10.2). The location of death varied, with 41.99% at home, 28.16% in medical facilities, 16.6% in nursing homes/long-term care facilities, 7.43% in hospices, and 5.80% at other/unknown places. Conclusion: There has been an overall improvement in AAMR among most ethnic groups, but an increase in AAMR has been observed among white individuals below the age of 55. Notably, over one-quarter of CRC-related deaths occur in medical facilities.

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.

Demographics and Trends of Hypertrophic Cardiomyopathy-Related Mortality in the United States, 1999-2020.

There are limited data on the mortality trends of HCM in the United States. To study the demographics and trends of mortality in patients with HCM, a retrospective cohort analysis was done with mortality data of patients with HCM listed as an underlying cause of death in the US Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research database (CDC-WONDER) from January 1999 to December 2020. The analysis took place in February 2022. First, we measured HCM-related age-adjusted mortality rate (AAMR) per 100,000 US population stratified by sex, race, ethnicity, and geographic area. We then calculated the Annual Percentage Change (APC) for AAMR for each. A total of 24,655 HCM-related deaths occurred between 1999 and 2020. The AAMR for HCM-related deaths declined from 0.5/100,000 patients in 1999 to 0.2 in 2020. The APC changes are as follows: -6.8 (95% CI: -11.8 to -1.5) from 2002 to 2009, -1.23 (95% CI -13.8 to 13.2) from 2009 to 2014, -6.71 (95% CI -46.2 to 61.7) from 2014 to 2017 and remained at 2.07 (95% CI -26.1 to 41.1) from 2017 to 2020. Men had consistently higher AAMR than women. Overall, AAMR in men was 0.4 (95% CI: 0.4-0.5), and in women was 0.3 (95% CI: 0.3-0.3). A similar trend was noticed in men and women over the years, starting from 1999 (AAMR men: 0.7 and women: 0.4) to 2020 (AAMR men: 0.3 and women: 0.2). AAMRs were highest among black or African American patients 0.6 (95% CI: 0.5-0.6), followed by non-Hispanic and Hispanic white 0.3 (95% CI 0.3-0.3) and Asian or Pacific Islander 0.2 (95% CI 0.2-0.2). There was substantial variation in each region in the US. States such as California, Ohio, Michigan, Oregon, and Wyoming had the highest AAMR. Large metropolitan cities had higher AAMR than non-metropolitan cities. During the study period from 1999 to 2020, HCM-related mortality steadily decreased. The highest AAMR was observed among men, black patients, and residents of metropolitan areas. States such as California, Ohio, Michigan, Oregon, and Wyoming had the highest AAMR.

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.
