Abstract

There is no detailed strain analysis of cardiac functions in treated hypertensive pediatric patients. The aim of this study was to evaluate the cardio-protective effects of different drug classes in treated pediatric hypertensive patients. Sixty non-obese-treated hypertensive patients with preserved left ventricular (LV) systolic function and 45 age-, sex-, and body mass index-matched healthy subjects underwent clinical evaluation, including 24-h ambulatory blood pressure monitoring, standard echocardiographic examination, tissue Doppler imaging, and two-dimensional Speckle Tracking Echocardiography. The patients were divided into two subgroups based on the effects of the drugs on the Renin Angiotensin Aldosterone System. The subgroup hypertension (HT) 1 received angiotensin-converting enzyme inhibitor or angiotensin receptor blocker, and HT 2 subgroup received calcium channel blocker, β-blocker, or diuretics. There was no difference between the two groups and subgroups with respect to clinical, demographic, ABPM, ventricular volumes, ejection fraction, and tissue Doppler imaging (TDI) parameters. For patients and controls, respectively, global longitudinal strain was - 18.70 ± 3.41 versus - 21.01 ± 3.82 (P < 0.001), and global...Continue Reading

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.

Antihypertensive Agents: Mechanisms of Action

Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.
