Introduction: High premature ventricular contraction (PVC) burden is known to cause atrial remodeling. P wave duration-to-amplitude ratio (PWDAR) is a new P wave index that includes both P wave duration and P wave voltage, which can be considered to effectively evaluate atrial cardiomyopathy. 3D speckle-tracking echocardiography is accepted as a valid and reliable technique for assessment of the left ventricle (LV) and left atrium (LA). Aim: In the present study, we investigated whether patients with a high PVC burden exhibit subclinical left atrial electrical and mechanical dysfunction, assessed electrically using PWDAR and mechanically using 3D-speckle tracking echocardiography. Material and methods: Seventy-five patients with PVC (PVC+) and 75 age- and gender-matched controls were enrolled in the study. Surface 12-lead standard electrocardiograms (ECGs) were recorded. Clinical characteristics and laboratory values of the patients were obtained. Conventional 2D echocardiographic and 3D-STE analyses were performed. Results: The PWDAR was significantly higher in the PVC+ group than in the control group (p < 0.001); and the LAS-r, LAS-active, and LV-GLS were significantly depressed in the PVC+ group (p < 0.001, p < 0.001, p = 0.015, respectively). The multivariate regression models demonstrated that PWDAR (p < 0.001), LAS-r (p < 0.001), LAS-active (p = 0.008), and LV-GLS (p = 0.021) were independent factors predicting PVC-induced atrial cardiomyopathy (PVC-ACMP). Conclusions: Our results revealed subclinical left atrial electrical and mechanical dysfunction in patients with a high PVC burden. PWDAR and left atrial strain parameters can predict PVC-ACMP.

Introduction: Hypertension is a significant public health concern and a contributor to cardiovascular conditions. Although physicians are essential in preventing and managing hypertension, limited research has been conducted on their own awareness of the condition. Aim: We aimed to examine the prevalence and awareness of hypertension among doctors in Turkey and identify relevant demographic and behavioral risk factors. Material and methods: A cross-sectional study was carried out with 178 physicians aged 25 to 64, randomly chosen from 35 healthcare institutions in 24 cities across Turkey. Data collection involved a structured questionnaire that examined hypertension awareness, sociodemographic details, and cardiovascular risk factors, complemented by standardized blood pressure assessments and body measurements. Hypertension was identified based on a systolic blood pressure of >= 140 mm Hg and/or a diastolic pressure of >= 90 mm Hg, self-reported diagnosis, or the use of antihypertensive drugs. Results: The overall prevalence of hypertension was 15.7%, with a significantly higher rate among males (20.2%) than females (7.8%) (p = 0.03). Age was a strong predictor, as individuals over 40 years had a markedly higher hypertension prevalence (27.9%) compared to those under 40 (4.3%) (p < 0.001). Body mass index (BMI), smoking, and physical inactivity were also significantly associated with hypertension. Among hypertensive doctors, awareness was 78.5%, though it did not show significant differences based on gender, BMI, or comorbidities. Conclusions: Despite relatively high awareness levels, hypertension remains prevalent among medical professionals, particularly in older and male doctors. Targeted strategies, such as routine screenings and lifestyle intervention programs, are essential to improve hypertension prevention and management in this population.
