AI Article Synopsis
- Venticular ectopic activity was observed in 5.6% of 12-lead ECGs and 8.2% of 2-minute rhythm strips among 4,674 subjects with isolated systolic hypertension in the SHEP study.
- The study found that 1.3% of participants had 6-10 ventricular premature beats (VPB), while 0.7% had more than 10 VPB; factors like older age, male sex, and low serum potassium levels were correlated with the presence of VPB.
- Higher numbers of VPB on the rhythm strip were associated with similar demographic and health factors, including a history of palpitations and specific heart patterns (Q/QS).
Article Abstract
Ventricular ectopic activity was recorded at baseline in 5.6% of the 12-lead electrocardiograms and 8.2% of the 2-minute rhythm strips of 4674 subjects with isolated systolic hypertension (systolic blood pressure 160 to 219 mm Hg, diastolic blood pressure < 90 mm Hg) participating in the Systolic Hypertension in the Elderly Program (SHEP). In this study 1.3% had 6 to 10 ventricular premature beats (VPB), and 0.7% had > 10 VPB on the 2-minute rhythm strip. Correlates of VPB presence on the 12-lead ECG were older-age male sex, presence of Q/QS pattern and higher heart rate. Participants with serum potassium < 3.5 mmol/L had a higher prevalence of VPB. Similarly, the number of VPB on the 2-minute rhythm strip was associated with male sex, increasing age, with lower serum potassium, history of palpitations, and presence of Q/QS patterns.

Division of Cardiology, Department of Internal Medicine, Keimyung University Dongsan Medical Center, Keimyung University School of Medicine, 1035 Dalgubeol-Daero, Dalseo-Gu, Daegu, 42601, Republic of Korea.
Background: With the growing number of high-risk pregnant women, echocardiography frequently reveals pericardial effusion (PE). However, the clinical implications of PE are unknown.
Method: We analyzed a cohort of 406 high-risk pregnant women who underwent echocardiography in the third trimester between November 2019 and December 2022.
Objective: ADHD is one of the most common neurodevelopmental disorders, seen in children and adolescents, and is often treated with various pharmacological agents, especially methylphenidate. There are differing opinions in the literature regarding the cardiovascular safety of long-term methylphenidate use. Studies suggest that the drug may increase the risk of hypertension, myocardial infarction, ventricular arrhythmia, sudden cardiac death, cardiomyopathy, heart failure (HF), pulmonary hypertension, and stroke.

Background: Exercise and its effect on cardiovascular diseases have been extensively studied in the elderly population. The difference in blood pressure (BP) between fit and unfit subjects can be >5 mmHg. It is not well established whether the positive effects of exercising on BP are associated with exercise type, be it aerobic or anaerobic (maximal muscle strength).

The purpose of this study was to investigate the feasibility of using F-labeled fibroblast activation protein inhibitor (FAPI) PET/CT in assessing the fibrotic remodeling of the pulmonary artery (PA) and the right ventricle (RV) in pulmonary arterial hypertension (PAH). In a rat model of monocrotaline-induced PAH, rats were euthanized at different time points for tissue analysis (fibroblast activation protein immunofluorescence and Masson's trichrome staining) after completing F-FAPI PET/CT and hemodynamic measurements. Thirty-eight PAH patients were enrolled to participate in F-FAPI PET/CT imaging, with right heart catheterization and echocardiography performed within 1 wk to assess pulmonary hemodynamics and cardiac function.
