The burden of cardiovascular disease in Asia from 2025 to 2050: a forecast analysis for East Asia, South Asia, South-East Asia, Central Asia, and high-income Asia Pacific regions.

Background: Given the rapidly growing burden of cardiovascular disease (CVD) in Asia, this study forecasts the CVD burden and associated risk factors in Asia from 2025 to 2050. Methods: Data from the Global Burden of Disease 2019 study was used to construct regression models predicting prevalence, mortality, and disability-adjusted life years (DALYs) attributed to CVD and risk factors in Asia in the coming decades. Findings: Between 2025 and 2050, crude cardiovascular mortality is expected to rise 91.2% despite a 23.0% decrease in the age-standardised cardiovascular mortality rate (ASMR). Ischaemic heart disease (115 deaths per 100,000 population) and stroke (63 deaths per 100,000 population) will remain leading drivers of ASMR in 2050. Central Asia will have the highest ASMR (676 deaths per 100,000 population), more than three-fold that of Asia overall (186 deaths per 100,000 population), while high-income Asia sub-regions will incur an ASMR of 22 deaths per 100,000 in 2050. High systolic blood pressure will contribute the highest ASMR throughout Asia (105 deaths per 100,000 population), except in Central Asia where high fasting plasma glucose will dominate (546 deaths per 100,000 population). Interpretation: This forecast forewarns an almost doubling in crude cardiovascular mortality by 2050 in Asia, with marked heterogeneity across sub-regions. Atherosclerotic diseases will continue to dominate, while high systolic blood pressure will be the leading risk factor.

Co-prevalence and incidence of myocardial infarction and/or stroke in patients with depression and/or anxiety: A systematic review and meta-analysis.

OBJECTIVE: Co-prevalence and incidence of depression and/or anxiety with stroke and myocardial infarction are currently unclear. This paper explores the relationships, as these are important comorbidities affecting patient outcomes. METHODS: A systematic search across five databases (PubMed, Scopus, PsycINFO, Embase, Cochrane) was conducted for observational studies reporting co-prevalence of depression or anxiety with stroke or myocardial infarction. We used random-effects models in all meta-analyses and evaluated heterogeneity using I2. RESULTS: This analysis included 48 studies with a total of 57,342 patients. In patients with depression, the pooled prevalence of stroke was 5.9% (95% CI = 5.53-6.37). In patients with myocardial infarction, the pooled prevalence of anxiety and depression was 9.1% (95% CI = 7.07-11.40, I2 = 85.6%) and 25.9% (95% CI = 18.46-34.12, I2 = 99.1%), respectively, and the pooled cumulative incidence of depression at one year was 20.5% (95% CI = 18.36-22.79). The pooled prevalence of anxiety and depression in patients with stroke was 13.5% (95% CI = 7.67-22.66, I2 = 96.9%) and 23.0% (95% CI = 17.93-28.99, I2 = 96.7%), respectively. The pooled cumulative incidences of depression at two weeks, three months, six months, and one year, were 29.1% (95% CI = 26.60-31.81), 17.0% (95% CI = 10.74-25.92, I2 = 98.0%), 7.4% (95% CI = 6.52-8.49), and 9.1% (95% CI = 3.71-20.79, I2 = 99.8%), respectively. CONCLUSIONS: This meta-analysis outlines the co-morbid burden between depression/anxiety and stroke/myocardial infarction. Future research should be done to evaluate the effectiveness of screening anxiety/depression in myocardial infarction/stroke.

The Impact of Cognitive Impairment on Clinical Outcomes After Transcatheter Aortic Valve Implantation (from a Systematic Review and Meta-Analysis).

This study sought to investigate the impact of pre-existing cognitive impairment on outcomes after transcatheter aortic valve implantation (TAVI). TAVI has been increasingly used in seniors, and evidence suggests better outcomes than surgical aortic valve replacement. Although frailty has been shown to be associated with poorer outcomes after TAVI, the effect of pre-existing cognitive impairment on patient outcomes after TAVI remains unclear. We searched the Medline, Embase, Scopus and Cochrane databases until May 14, 2022. The risk of bias was assessed using the Newcastle-Ottawa scale. The primary outcome was short-term (6 months to 1 year) mortality, and secondary outcomes included long-term (1 year to 3 years) mortality, in-hospital mortality, and postoperative delirium. A total of 14 studies with 32,746 patients (5,098 patients with cognitive impairment at baseline, 27,648 without) were included in our meta-analysis. Among studies that reported the raw proportion of patients with mortality of postoperative delirium, cognitive impairment significantly increased mortality (risk ratio 2.10, 95% confidence intervals [CIs] 1.43 to 3.08, p = 0.0002) and postoperative delirium (risk ratio 2.27, 95% CI 1.76 to 2.93, p <0.0001). Studies which reported the hazards for mortality (pooled hazards ratio 1.97, 95% CI 1.50 to 2.60, p <0.0001) and odds of postoperative delirium (pooled odds ratio 2.40, 95% CI: 1.51 to 3.80, p = 0.0002) yielded results consistent with the primary meta-analysis. In conclusion, pre-existing cognitive impairment is a significant risk factor for poorer outcomes after TAVI and should be carefully considered in this group of patients. Guidelines and future studies should take cognitive impairment into consideration for preoperative risk stratification.
