Abstract

To determine the usefulness of monitoring morning blood pressure surge (MBPS) to predict cardiovascular events in patients with essential hypertension. A total of 81 patients (43 males and 38 females) with a mean age of 55.9 ± 9.8 years with essential hypertension were included in the study. Twenty-four hour ambulatory blood pressure (BP) monitoring was carried out to record MBPS. All patients were followed up for 36 months for cardiovascular events. Mean MBPS was 26.23 ± 10.17 mmHg. Nineteen patients (23%) who experienced a cardiovascular event during the follow-up period had higher MBPS than patients who did not experience a cardiovascular event (P < 0.0001). MBPS was positively correlated with interventricular septum thickness (r = +0.38 and P = 0.000), left atrial size (r = +0.39 and P = 0.000), 24-h mean systolic BP (r = +0.36 and P = 0.001) and total cholesterol level (r = +0.23 and P = 0.003). MBPS was negatively correlated with high-density lipoprotein-cholesterol (r = -0.37 and P = 0.001). MBPS can be used as a biomarker for a cardiovascular disease event in hypertensive patients.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
