An Intervention programme has been designed to facilitate patient in understanding and improving their health condition and quality of life. But, why some patients who have undergone an intervention do well while others do not still remain a question to the health practitioners. The limited amount of literature on the factors contributing to these discrepancies has triggered me to explore the determinants of successful control of hypertension among those attending the intervention programme in Malaysia. Thus, this monograph, elaborates the discrepencies and determinants of successful control of hypertension from Malaysian patients'' perspective.This analysis should be useful for health practitioners from various disciplines to understand the determinants and endurance of discrepancy in the successful control of hypertension among Malaysian patients.
