Mortality, Revascularization, and Cardioprotective Pharmacotherapy After Acute Coronary Syndrome in Patients With Psychotic Disorders: A Population-Based Cohort Study.

ABSTRACT: Ischemic heart disease is the leading cause of mortality in psychotic disorders. There is a paucity of research comprehensively evaluating short-term mortality, cardiovascular complications, and treatment inequality after cardiac events in patients with psychotic disorders. This population-based cohort study examined 30-day and 1-year all-cause mortality, cardiovascular complication rates, 30-day and 1-year receipt of invasive cardiac procedures, and 90-day post-discharge cardioprotective medication treatment following admission for first-recorded acute coronary syndrome (ACS) among patients with psychotic disorders (n = 703) compared with patients without psychotic disorders (n = 66 989) between January 2006 and December 2016 in Hong Kong (HK). Study data were retrieved from territory-wide medical record database of public healthcare services to 7.5 million HK residents. Multivariate regression analyses (ORs and 95% CIs), adjusting for demographics and medical comorbidities, were conducted to evaluate associations between psychotic disorders and post-ACS outcomes. Our results showed that patients with psychotic disorders had higher 30-day (OR: 1.99 [95% CI: 1.65-2.39]) and 1-year (2.13 [1.79-2.54]) mortality, and cardiovascular complication rates (1.20 [1.02-1.41]), lower receipt of cardiac catheterization (30-d: 0.54 [0.43-0.68]; 1-y: 0.46 [0.38-0.56]), percutaneous coronary intervention (30-d: 0.55 [0.44-0.70]; 1-y: 0.52 [0.42-0.63]) and reduced β-blockers (0.81 [0.68-0.97]), statins (0.54 [0.44-0.66]), and clopidogrel prescriptions (0.66 [0.55-0.80]). Associations between psychotic disorder and increased mortality remained significant even after complications and treatment receipt were additionally adjusted. Our findings indicate that psychotic disorders are associated with increased risks of short-term post-ACS mortality, cardiovascular complications, and inferior treatment. Excess mortality is not substantially explained by treatment inequality. Further investigation is warranted to clarify factors for suboptimal cardiac-care and elevated mortality in psychotic disorders to enhance post-ACS outcome.

Project description:Studies have suggested that complete revascularization is superior to culprit-only revascularization for the treatment of enzyme-positive acute coronary syndrome. However, the optimal timing of complete revascularization remains unclear. We conducted a systematic review and meta-analysis of randomized controlled trials comparing single-stage complete revascularization with multistage percutaneous coronary intervention in patients with ST-segment elevation myocardial infarction or non-ST-segment elevation myocardial infarction with multivessel disease. We systematically searched the Cochrane Central Register of Controlled Trials, Embase, PubMed, and MEDLINE for randomized controlled trials comparing single-stage complete revascularization with multistage revascularization in patients with enzyme-positive acute coronary syndrome. The primary outcome was the incidence of major adverse cardiovascular events at longest follow-up. Data were pooled using DerSimonian and Laird random-effects models. Four randomized controlled trials (n=838) were included in our meta-analysis. The risk of unplanned repeat revascularization at longest follow-up was significantly lower in patients randomized to single-stage complete revascularization (risk ratio, 0.68; 95% CI, 0.47-0.99). Results also suggest a trend towards lower risks of major adverse cardiovascular events for patients randomized to single-stage revascularization at 6 months (risk ratio, 0.67; 95% CI, 0.40-1.11) and at longest follow-up (risk ratio, 0.79; 95% CI, 0.52-1.20). Risks of mortality and recurrent myocardial infarction at longest follow-up were also lower with single-stage revascularization, but 95% CIs were wide and included unity. Our results suggest that single-stage complete revascularization is safe. There also appears to be a trend towards lower long-term risks of mortality and major adverse cardiovascular events; however, additional randomized controlled trials are required to confirm the potential benefits of single-stage multivessel percutaneous coronary intervention.

Project description:BackgroundThere is limited evidence on the use of high-sensitivity C-reactive protein (hsCRP) as a biomarker for selecting patients for advanced cardiovascular (CV) therapies in the modern era. The prognostic value of mildly elevated hsCRP beyond troponin in a large real-world cohort of unselected patients presenting with suspected acute coronary syndrome (ACS) is unknown. We evaluated whether a mildly elevated hsCRP (up to 15 mg/L) was associated with mortality risk, beyond troponin level, in patients with suspected ACS.Methods and findingsWe conducted a retrospective cohort study based on the National Institute for Health Research Health Informatics Collaborative data of 257,948 patients with suspected ACS who had a troponin measured at 5 cardiac centres in the United Kingdom between 2010 and 2017. Patients were divided into 4 hsCRP groups (<2, 2 to 4.9, 5 to 9.9, and 10 to 15 mg/L). The main outcome measure was mortality within 3 years of index presentation. The association between hsCRP levels and all-cause mortality was assessed using multivariable Cox regression analysis adjusted for age, sex, haemoglobin, white cell count (WCC), platelet count, creatinine, and troponin. Following the exclusion criteria, there were 102,337 patients included in the analysis (hsCRP <2 mg/L (n = 38,390), 2 to 4.9 mg/L (n = 27,397), 5 to 9.9 mg/L (n = 26,957), and 10 to 15 mg/L (n = 9,593)). On multivariable Cox regression analysis, there was a positive and graded relationship between hsCRP level and mortality at baseline, which remained at 3 years (hazard ratio (HR) (95% CI) of 1.32 (1.18 to 1.48) for those with hsCRP 2.0 to 4.9 mg/L and 1.40 (1.26 to 1.57) and 2.00 (1.75 to 2.28) for those with hsCRP 5 to 9.9 mg/L and 10 to 15 mg/L, respectively. This relationship was independent of troponin in all suspected ACS patients and was further verified in those who were confirmed to have an ACS diagnosis by clinical coding. The main limitation of our study is that we did not have data on underlying cause of death; however, the exclusion of those with abnormal WCC or hsCRP levels >15 mg/L makes it unlikely that sepsis was a major contributor.ConclusionsThese multicentre, real-world data from a large cohort of patients with suspected ACS suggest that mildly elevated hsCRP (up to 15 mg/L) may be a clinically meaningful prognostic marker beyond troponin and point to its potential utility in selecting patients for novel treatments targeting inflammation.Trial registrationClinicalTrials.gov - NCT03507309.

Project description:AimsCoronary artery disease (CAD) is a common cause of heart failure (HF). It remains unclear who, when and why to direct towards coronary revascularization. The outcomes of coronary revascularization in HF patients are still a matter of debate nowadays. This study aims to evaluate the effect of revascularization strategy on all-cause of death in the context of ischaemic HF.Methods and resultsAn observational cohort was conducted on 692 consecutive patients who underwent coronary angiography at the University Hospital of Toulouse between January 2018 and December 2021 for either a recent diagnosis of HF or a decompensated chronic HF, and in whom coronary angiograms showed at least 50% obstructive coronary lesion. The study population was divided into two groups according to the performance or not of a coronary revascularization procedure. The living status (alive or dead) of each of the study's participants was observed by April 2022. Seventy-three per cent of the study population underwent coronary revascularization either by percutaneous coronary intervention (66.6%) or coronary artery bypass grafting (6.2%). Baseline characteristics including age, sex and cardiovascular risk factors did not differ between the invasive and conservative groups, respectively. Death occurred in 162 study participants resulting in an all-cause mortality rate of 23.5%; 26.7% of observed deaths have occurred in the conservative group versus 22.2% in the invasive group (P = 0.208). No difference in survival outcomes has been observed over a mean follow-up period of 2.5 years (P = 0.140) even after stratification by HF categories (P = 0.132) or revascularization modalities (P = 0.366).ConclusionsFindings from the present study showed comparable all-cause mortality rates between groups. Coronary revascularization does not modify short-term survival outcomes in HF patients compared with optimal medical therapy alone outside the setting of acute coronary syndrome.
