History of coronary heart disease increased the mortality rate of patients with COVID-19: a nested case-control study.

ABSTRACT: OBJECTIVE:Evaluate the risk of pre-existing comorbidities on COVID-19 mortality, and provide clinical suggestions accordingly. SETTING:A nested case-control design using confirmed case reports released from the news or the national/provincial/municipal health commissions of China between 18 December 2019 and 8 March 2020. PARTICIPANTS:Patients with confirmed SARS-CoV-2 infection, excluding asymptomatic patients, in mainland China outside of Hubei Province. OUTCOME MEASURES:Patient demographics, survival time and status, and history of comorbidities. METHOD:A total of 94 publicly reported deaths in locations outside of Hubei Province, mainland China, were included as cases. Each case was matched with up to three controls, based on gender and age ±1 year old (94 cases and 181 controls). The inverse probability-weighted Cox proportional hazard model was performed, controlling for age, gender and the early period of the outbreak. RESULTS:Of the 94 cases, the median age was 72.5 years old (IQR=16), and 59.6% were men, while in the control group the median age was 67 years old (IQR=22), and 64.6% were men. Adjusting for age, gender and the early period of the outbreak, poor health conditions were associated with a higher risk of COVID-19 mortality (HR of comorbidity score, 1.31 [95% CI 1.11 to 1.54]; p=0.001). The estimated mortality risk in patients with pre-existing coronary heart disease (CHD) was three times that of those without CHD (p<0.001). The estimated 30-day survival probability for a profile patient with pre-existing CHD (65-year-old woman with no other comorbidities) was 0.53 (95% CI 0.34 to 0.82), while it was 0.85 (95% CI 0.79 to 0.91) for those without CHD. Older age was also associated with increased mortality risk: every 1-year increase in age was associated with a 4% increased risk of mortality (p<0.001). CONCLUSION:Extra care and early medical interventions are needed for patients with pre-existing comorbidities, especially CHD.

Project description:Identifying environmentally responsive genetic loci where DNA methylation is associated with coronary heart disease (CHD) may reveal novel pathways or therapeutic targets for CHD. We conducted the first prospective epigenome-wide analysis of DNA methylation in relation to incident CHD in the Asian population. We did a nested case-control study comprising incident CHD cases and 1:1 matched controls who were identified from the 10 year follow-up of the China Kadoorie Biobank. Methylation level of baseline blood leukocyte DNA was measured by Infinium Methylation EPIC BeadChip. We performed the single cytosine-phosphate-guanine (CpG) site association analysis and network approach to identify CHD-associated CpG sites and co-methylation gene module. After quality control, 982 participants (mean age 50.1 years) were retained. Methylation level at 25 CpG sites across the genome was associated with incident CHD (genome-wide false discovery rate [FDR] < 0.05 or module-specific FDR < 0.01). One SD increase in methylation level of identified CpGs was associated with differences in CHD risk, ranging from a 47 % decrease to a 118 % increase. Mediation analyses revealed 28.5 % of the excessed CHD risk associated with smoking was mediated by methylation level at the promoter region of ANKS1A gene (P for mediation effect = 0.036). Methylation level at the promoter region of SNX30 was associated with blood pressure and subsequent risk of CHD, with the mediating proportion to be 7.7 % (P = 0.003) via systolic blood pressure and 6.4 % (P = 0.006) via diastolic blood pressure. Network analysis revealed a co-methylation module associated with CHD. We identified novel blood methylation alterations associated with incident CHD in the Asian population and provided evidence of the possible role of epigenetic regulations in the smoking- and blood pressure-related pathways to CHD risk.

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.
