Homocysteine and Early Diastolic Dysfunction in Newly Diagnosed Hypertension

Recruiting now

Conditions studied: Hypertension (HTN), Hyperhomocysteinemia, Diastolic Dysfunction

In brief

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.
