Echocardiographic diastolic dysfunction among hypertensive patients

Abstract

Background and objective: Hypertension is a very common medical disorder, affecting nearly 40% of our population. Diastolic dysfunction is one of complications that happens and is regarded as a predictive of subsequent heart failure. The aim of this study was to determine the frequency of left ventricular diastolic dysfunction by echocardiography among hypertensive patients. Methods: This study involved 150 hypertensive cases (82 female and 68 male) age from 25-81 years old. Transthoracic echocardiography approach, using SIEMENS SONOLINE Omnia 2005 machine with the probe of p4-2 was used by the researcher. A comparative 150 normal non-hypertensive healthy adults with hypertensive patients are examined again by echocardiography. The parameter for the diastolic dysfunction measurement is E/A ratio. Results: It was found that 88 (58.7%) of hypertensive patients have diastolic dysfunction, while 4.9% of non-hypertensive group have diastolic dysfunction with significant statistical differences between both groups (P <0.001), who were age >60years have 79%, while age 25-35years old have 21% (P <0.001). Among left ventricular hypertrophy patients, 87.5%, versus 12.5% have diastolic dysfunction (P <0.001). Females are more liable for diastolic dysfunction, who have 70.7% than males who have 44.1% (P <0.001). Conclusion: Diastolic dysfunction is common among hypertensive patients, particularly among females, aged, and who have echocardiographic criteria of left ventricular hypertrophy, represent risk factors for diastolic dysfunction.
