Abstract
Coronary artery disease is leading cause of mortality and morbidity worldwide. Uncontrolled hypertension is one of the most common determinant for hospital admissions due to acute coronary events. Computed tomographic (CT) coronary calcium scoring has been established as the best noninvasive predictor of atherosclerotic cardiovascular risk available today.
The present study aimed to evaluate the extent of coronary artery calcium (CAC) in hypertensive patients using MSCT. The study recruited 90 patients with recurrent chest pain referred for Coronary MSCT angiography. They comprised 69 hypertensive patients and 21 normotensive patients. All patients were subjected to careful history taking, thorough clinical examination and laboratory investigations. CT angiography was performed to all patients and coronary artery calcium score was calculated.
Comparison between hypertensive and non-hypertensive patients regarding the CT angiographic data revealed that patients with hypertension had significantly higher rate of 1-49 % proximal LAD obstruction when compared with non-hypertensive patients. In addition, they had significantly higher rate of mid LCX 1-49 % and ≥ 50 % obstruction when compared with non-hypertensive patients. Also, it was shown that non-hypertensive patients had significantly higher number of patients with non-affected vessels. Hypertensive patients had significantly higher rate of 2 vessels affection.
In the current study, it was also found that hypertensive patients had significantly CACS, ABOS, SIS, SSS and syntax I scores when compared with non-hypertensive patients.
