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.

Routine Functional Testing or Standard Care in High-Risk Patients after Percutaneous Coronary Intervention.

PURPOSE OF REVIEW: This review aimed to collate the available evidence on outcomes following routine functional stress testing vs standard of care (i.e. symptom-guided stress testing) in high-risk patients following percutaneous coronary intervention (PCI). RECENT FINDINGS: The most recent pragmatic POST-PCI trial provided randomized evidence showing that routine functional stress testing post-PCI did not lead to a reduction in 2-year ischemic cardiovascular events or all-cause mortality, as compared to a symptom-guided standard-of-care approach. This was also true for sub-analyses including multivessel or left main disease, diabetics, as well as following imaging or physiology guided PCI. In the absence of a change in their clinical or functional status suggestive of stent failure, post-PCI routine periodic stress testing in stable patients on guideline-directed medical therapy is currently not recommended by American clinical practice guidelines. While evidence on the cost-effectiveness of routine stress testing strategy is scarce, physician, payer, and policy-level interventions to reduce inappropriate use of routine functional testing need to be addressed.

A case report: anteroseptal ST elevation due to acute isolated right ventricular infarction.

BACKGROUND: Electrocardiogram (ECG) is the first diagnostic tool physicians use in diagnosing acute myocardial infarction (MI). In this case report, we present a case where the initial ECG diagnosis was that of an acute anteroseptal MI but emergency coronary angiography showed that the infarct-related artery was a small non-dominant right coronary artery (RCA) instead of the anticipated left anterior descending artery (LAD). Isolated right ventricular (RV) infarction from a non-dominant RCA is rarely seen in clinical practice, and it may exhibit ECG changes that can be confused with an acute anteroseptal MI. It is important to appreciate the subtle differences in the ECG changes that occur in either of these two types of MI for appropriate diagnosis and treatment. CASE PRESENTATION: A 49-year-old non-smoking male with prior coronary stent implantation in LAD presented with acute chest pain and his pre-hospital ECG indicated an anteroseptal STEMI possibly due to stent thrombosis, but an emergency angiogram showed patent LAD and Circumflex arteries. There was however thrombotic occlusion of the right, non-dominant coronary artery, which was revascularized with a drug-eluting stent. The patient's chest pain and ST elevations resolved, and subsequent echo showed moderate RV systolic dysfunction in keeping with RV myocardial infarction. DISCUSSION: RV myocardial infarction is usually due to an occlusion of the dominant RCA proximal to the origin of its RV wall branch, which often results in inferior ST elevation with reciprocal anterior ST depression. The ST elevation over V1 which would accompany RV infarction is often masked due to the more dominant electrical forces of inferior and posterior LV wall infarction. Our case demonstrates that in isolated RV infarction due to non-dominant proximal RCA occlusion, anterior ST elevation can be seen over V1-3, being most prominent in V1, which overlies the right ventricle, and resolved after restoring flow to the RCA. Spatial vector analysis of the ECG or right-sided ECG leads would be helpful to aid the diagnosis of RV infarction when clinical suspicion is present, for example when there is significant hypotension, raised jugular venous pressure but clear lung fields or deterioration after nitrate administration.

Higher risk of adverse cardiovascular outcomes in females with type 2 diabetes Mellitus: an Umbrella review of systematic reviews.

BACKGROUND: Previous studies have shown that females with type 2 diabetes mellitus (T2DM) may have excess mortality risk compared to their male counterparts. An important next step to address the high global burden of T2DM and cardiovascular disease (CVD) is an umbrella review to summarize data on sex differences in cardiovascular outcomes for patients with T2DM and assess the strength of the evidence observed. METHODS AND RESULTS: Medline and Embase were searched from inception till 7 August 2022 for systematic reviews and meta-analyses studying the effects of sex on cardiovascular outcomes in T2DM patients. Results from reviews were synthesized with a narrative synthesis, with a tabular presentation of findings and forest plots for reviews that performed a meta-analysis. 27 review articles evaluating sex differences in cardiovascular outcomes were included. Females with T2DM had a higher risk of developing coronary heart disease (CHD; RRR: 1.52, 95%CI: 1.32-1.76, P < 0.001), acute coronary syndrome (ACS; RRR: 1.38, 95%CI: 1.25-1.52, P < 0.001), heart failure (RRR: 1.09, 95%CI: 1.05-1.13, P < 0.001) than males. Females had a higher risk of all-cause mortality (RRR: 1.13, 95%CI: 1.07-1.19, P < 0.001), cardiac mortality (RRR: 1.49, 95%CI: 1.11-2.00, P = 0.009) and CHD mortality (RRR: 1.44, 95%CI: 1.20-1.73, P < 0.001) as compared to males. CONCLUSIONS: This umbrella review demonstrates that females with T2DM have a higher risk of cardiovascular outcomes than their male counterparts. Future research should address the basis of this heterogeneity and epidemiological factors for better quality of evidence, and identify actionable interventions that will narrow these sex disparities.

This umbrella review highlights the sex differences in adverse cardiovascular events in patients with type 2 diabetes mellitus (T2DM), with females at a higher risk than males. This is contributed by both biological and healthcare disparities and underscores the need for equitable care and personalized medical therapy.Females with T2DM have a higher risk of coronary heart disease, acute coronary syndrome, heart failure, and cardiac mortality compared to males.Clinicians need to be aware of the substantial heterogeneity across the current T2DM studies, and future meta-analysis and large-scale studies examining sex differences in outcomes should attempt to address the heterogeneity and epidemiological factors for a better quality of evidence.

Young mother with lupus and life-altering cardiocerebrovascular nightmare: a case report.

Background: Systemic lupus erythematosus (SLE) predominantly affects women and increases their cardiovascular disease risk up to three-fold. Young women with SLE face various challenges and gender-specific issues, especially concerning pregnancy. Case summary: A female patient, 37 years old, married with two children, hospitalized for SLE, consulted for chest pain, shortness of breath, and dry cough. She quit her medication in the past 7 years prior to her admission in the hope of conceiving. Physical examinations showed signs of heart failure. Electrocardiogram revealed recent myocardial infarction. She had increased hs-Troponin T 180.3 pg/mL and NTproBNP 13 419 ng/L. An echocardiogram demonstrated a low ejection fraction at 30.4%, left ventricle thrombus, and wall motion abnormalities. The angiogram showed severe coronary artery disease. Her condition was then complicated by embolic stroke and recurrent bleeding from anticoagulant subcutaneous punctured sites. Discussion: Patients with SLE are prone to hypercoagulability and accelerated atherosclerosis, which may lead to pre-mature mortality. In this case, balancing risk for bleeding vs. ischaemia is a see-saw decision. The current risk scores do not cater specifically to this population, but the existing ones suggest this patient will have an equally undesired outcome. Hence, a multi-disciplinary team discussion was needed. Considering the immense risk of any intervention at the time, the decision was to administer a conservative treatment. Conclusion: Recognizing and anticipating gender-specific issues in managing patients with SLE are keys to preventing catastrophic complications. Multi-disciplinary team involvement is critical in dealing with complex cases.
