Diastolic Dysfunction

The goal of this observational study is to learn if weight loss surgery can lower fat inside the heart muscle and improve how the heart relaxes in adults with obesity. The main questions it aims to answer are: Does fat inside the heart muscle decrease after weight loss surgery? Does heart relaxation (diastolic function) improve after surgery? Are changes in heart fat linked to changes in weight, body fat, and blood markers? Participants who are already planning to have weight loss surgery will take part in this study. Participants will: Have a heart CT scan to measure fat in the heart muscle before surgery and about 6 months after surgery Have an ultrasound of the heart (echocardiogram) to check how the heart fills and relaxes Have body composition testing to measure fat and muscle Have blood tests, including routine tests and additional markers related to heart function and metabolism Researchers will compare each participant's results before and after surgery to see if heart fat decreases and if heart function and blood markers improve.

This prospective single-center observational study aims to evaluate the relationship between elevated plasma homocysteine levels and early echocardiographic abnormalities in patients with newly diagnosed essential hypertension. Adult patients diagnosed with essential hypertension within the previous 6 months will undergo clinical assessment, ambulatory blood pressure monitoring, electrocardiography, laboratory testing, and comprehensive transthoracic echocardiography including diastolic function assessment and strain analysis when image quality is adequate. Participants will be classified according to plasma homocysteine level using, and patients with elevated and normal homocysteine levels will be compared with respect to diastolic dysfunction and left ventricular and left atrial global longitudinal strain parameters. Clinical, laboratory, and echocardiographic data will also be used to develop a machine-learning based model for prediction of H-type hypertension.

Two recently developed artificial intelligence-enabled electrocardiogram (AI-ECG) models have been developed to detect aortic stenosis (AS) and diastolic dysfunction (DD). AI-ECG for AS has a sensitivity of 78% and specificity of 74%, and AI-ECG for DD has a sensitivity of 83% and specificity of 80%. However, these models have never been prospectively applied to diagnose AS or DD, which may be useful for patients and providers from a diagnostic and prognostic perspective and especially in settings where access to higher- level medical care is limited. In this study, we aim to determine the clinical utility of these AI-ECG models by prospectively applying them to an outpatient cohort and then completing a focused point-of-care ultrasound to evaluate those who are AI-ECG positive for AS and DD.

The goal of this observational cross-sectional study is to assess the prevalence of left ventricular diastolic dysfunction and identify associated risk factors in health-care workers of various ages and both sexes. The main questions it aims to answer are: What is the prevalence of diastolic dysfunction among healthcare workers? Which occupational, lifestyle, or clinical factors are associated with abnormal diastolic function in this population? Researchers will compare health-care workers who dont need night shift with those who have to. Participants will: Complete questionnaires regarding demographic information, work schedules, lifestyle factors, and medical history. Undergo echocardiographic examination to assess diastolic function. Receive basic vital sign by ambulatory blood pressure monotoring.

The aim of the study was to determine the rehabilitative effects of 12-week variable intensity swimming exercises on the cardiovascular system in women with diastolic dysfunction. Studies on how variable intensity swimming exercises contribute to the course of the disease in sedentary women with cardiovascular problems are limited. Previous studies generally consisted of studies on the effects of exercise applications on the cardiovascular system in different branches and their effects were determined.

The purpose of the study is to evaluate the presence of early vascular aging 6 months and 12 months after COVID-19 infection.

The purpose of this study is to examine the impact of early surgery in patients with asymptomatic severe aortic valve stenosis with signs of subclinical LV dysfunction despite preserved LVEF, with a watchfull waiting approach.
