Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial
Background
Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy
NON-INVASIVE ASSESSMENT OF MYOCARDIAL ENERGETICS USING 11-C ACETATE POSITRON EMISSION TOMOGRAPHY: SYSTEMATIC REVIEW AND META-ANALYSIS
Background: 11-C acetate PET is a non-invasive imaging modality to assess myocardial oxygen consumption (MVO2), and external efficiency (MEE). We conducted a systematic review and meta-analysis of available literature on this topic.
Methods: We searched electronic databases from inception to September 15, 2021, for all studies using 11C-Acetate PET in humans and patients with CVD at rest. Data are presented as mean with 95% CI.
Results: 54 studies with 1,182 participants (337 healthy, 845 patients with any CVD) met our inclusion criteria. Mean MVO2 and MEE in studies with healthy controls was 0.11 (0.09, 0.13, I2=99.3%) ml min-1g-1 and 27% (22, 33 I2=98.3%), respectively (Figure). Mean MEE in HFrEF, HFpEF, AS and HCM was 15% (13, 18), 13% (12, 14), 23% (20, 25) and 19% (CI 17, 22), respectively. In HFrEF, both mean MVO2 (difference -0.02,-0.03, -0.01) and MEE (difference -9%, [-13, -6]) were lower vs. healthy controls. In HFpEF, mean MVO2 was higher (difference 0.03, -0.01, 0.07), but mean MEE was similar. In aortic stenosis, mean MVO2 was higher (difference 0.03, [0.01, 0.05]) and mean MEE lower (difference -7%, [-16, 1]) vs. healthy controls. In HCM, mean MVO2 was higher (WMD 0.01, [0.00, 0.02]), and mean MEE was lower (difference -21%, [-33, -8]).
Conclusion: Assessment of myocardial energetics using 11-C acetate PET can help understand the pathophysiology of distinct CVD. There is significant heterogeneity in the current literature, and there is an unmet need to standardize protocols and reporting methods
The pandemic of coronary heart disease in South Asia: What clinicians need to know
Purpose of review: South Asia has around 1/6th of the current global population. Epidemiological studies suggest that South Asians living in South Asia and diaspora are at an increased risk of premature atherosclerotic cardiovascular diseases (ASCVDs). This is due to an interplay of genetic, acquired, and environmental risk factors. Due to its increasing share of the global population, clinicians need to know the reasons for this early predisposition, and strategies for early identification and mitigation. Recent findings: South Asians have earlier onset of cardiometabolic risk factors such as insulin resistance, hypertension, and central adiposity. This increased risk is seen in both native South Asians and the diaspora. South Asians have earlier onset of ASCVD due to an earlier onset of cardiometabolic risk factors. Health promotion and early identification of these risk factors are essential to mitigate this ongoing crisi
Comparing eligibility for statin therapy for primary prevention under 2022 USPSTF recommendations and the 2018 AHA/ACC/ multi-society guideline recommendations: From National Health and Nutrition Examination Survey
Introduction: The United States Preventive Services Taskforce (USPSTF) recently released recommendations for statin therapy eligibility for the primary prevention of cardiovascular disease (CVD). We report the proportion and the absolute number of US adults who would be eligible for statin therapy under these recommendations and compare them with the previously published 2018 American Heart Association (AHA)/ American College of Cardiology (ACC)/ Multisociety (MS) Cholesterol guidelines.Methods: We used data from the National Health and Nutrition Examination Survey (NHANES) 2017-2020 of adults aged 40-75 years without prevalent self-reported atherosclerotic CVD (ASCVD) and low-density lipoprotein-cholesterol \u3c190 mg/dL. The 2022 USPSTF recommends statin therapy for primary prevention in those with a 10-year ASCVD risk of ≥10% and ≥ 1 CVD risk factor (diabetes mellitus, dyslipidemia, hypertension, or smoking). The 2018 AHA/ ACC/ MS Cholesterol guideline recommends considering statin therapy for primary prevention for those with diabetes mellitus, or 10-year ASCVD risk ≥20% or 10-year ASCVD risk 7.5 to \u3c20% after accounting for risk-enhancers and shared decision making. Survey recommended weights were used to project these proportions to national estimates.Results: Among 1799 participants eligible for this study, the weighted mean age was 56.0 ± 0.5 years, with 53.0% women (95% confidence interval [CI] 49.7, 56.3), and 10.6% self-reported NH Black individuals (95% CI 7.7, 14.3). The weighted mean 10-year ASCVD risk was 9.6 ± 0.3%. The 2022 USPSTF recommendations and the 2018 AHA/ ACC/ MS Cholesterol guidelines indicated eligibility for statin therapy in 31.8% (95% CI 28.6, 35.1) and 46.8% (95% CI 43.0, 50.5) adults, respectively. These represent 33.7 million (95% CI 30.4, 37.2) and 49.7 million (95% CI 45.7, 53.7) adults, respectively. For those with diabetes mellitus, 2022 USPSTF recommended statin therapy in 63.0% (95% CI 52.1, 72.7) adults as compared with all adults with diabetes aged 40-75 years under the 2018 AHA/ ACC/ MS Cholesterol guidelines.Conclusion: In this analysis of the nationally representative US population from 2017 to 2020, approximately 15% (~16.0 million) fewer adults were eligible for statin therapy for primary prevention under the 2022 USPSTF recommendations as compared to the 2018 AHA/ ACC/ MS Cholesterol guideline
Impact of the 2017 ACC/AHA guidelines on the prevalence of hypertension among Indian adults: Results from a cross-sectional survey
© 2020 The Authors Background: The impact of the 2017 American College of Cardiology (ACC)/American Heart Association (AHA) guidelines for diagnosis and management of hypertension on the prevalence of hypertension in India is unknown. Methods: We analyzed data from the Cardiac Prevent 2015 survey to estimate the change in the prevalence of hypertension. The JNC8 guidelines defined hypertension as a systolic blood pressure of ≥140 ​mmHg or diastolic blood pressure of ≥90 ​mmHg. The 2017 ACC/AHA guidelines define hypertension as a systolic blood pressure of ≥130 ​mmHg or diastolic blood pressure of ≥80 ​mmHg. We standardized the prevalence as per the 2011 census population of India. We also calculated the prevalence as per the World Health Organization (WHO) World Standard Population (2000–2025). Results: Among 180,335 participants (33.2% women), the mean age was 40.6 ​± ​14.9 years (41.1 ​± ​15.0 and 39.7 ​± ​14.7 years in men and women, respectively). Among them, 8,898 (4.9%), 99,791 (55.3%), 35,694 (11.9%), 23,084 (12.8%), 9,989 (5.5%) and 2,878 (1.6%) participants belonged to age group 18–19, 20–44, 45–54, 55–64, 65–74 and ​≥ ​75 years respectively. The prevalence of hypertension according to the JNC8 and 2017 ACC/AHA guidelines was 29.7% and 63.8%, respectively- an increase of 115%. With the 2011 census population of India, this suggests that currently, 486 million Indian adults have hypertension according to the 2017 ACC/AHA guidelines, an addition of 260 million as compared to the JNC8 guidelines. Conclusion: According to the 2017 ACC/AHA guidelines, 3 in every 5 Indian adults have hypertension
