INTRODUCTIONMajority of patients (>90%) with hypertension suffer from essential or primary hypertension, while the remaining minority have secondary hypertension. It is estimated that only one-third of patients on treatment have their blood pressures well controlled.1 A considerable percentage of poorly control falls into a category known as 'resistant hypertension' of which pathophysiology and risk factors are not fully understood. 2Resistant hypertension is defined as "Suboptimal control of blood pressure despite using three antihypertensive agents inclusive of a diuretic, and patients who need ≥4drugs to control blood pressure".2 Despite having guidelines on management of resistant hypertension, it has become a problem to control blood pressure up to recommended levels, possibly due to poor understanding of pathophysiology and risk factors. Studies have shown that older age, obesity, excessive use of alcohol, and high sodium intake are strongly correlated with poor control of hypertension.3,4 Patient factors such as compliance and knowledge, and healthcare system factors like limitation of resources and lack of reminders of appointments also plays a major role in poor blood pressure control. [5][6][7][8][9] Managing resistant hypertension is difficult and they are more likely to have target organ damage and have higher cardiovascular risks than patients with well controlled blood pressure. 10 The prevalence rate for hypertension in urban India is 29-45% in men and 25-38% in women, while data from other South Asian countries are sparse.

Methods: A descriptive cross-sectional observational study was carried out among 300 hypertensive patients attending 'Hypertension Clinic' and providing informed written consent from October 2013 to December 2013 at Burdwan Medical College and Hospital, Burdwan, West Bengal in India. A pre-tested interviewer-administered questionnaire was used for data collection. Chi-squire test and odds ratio were calculated using biomedical software. The study was approved by Ethics Review Committee of our Institution. Results: The prevalence of resistant hypertension was 23.33% among all hypertensives. The patients with Resistant hypertension were significantly associated with older age groups (>55 years) (77.1% vs. 38.3%, p value <0.001, OR 5.446, 95% CI 2.935 and 10.104), Obesity (BMI > 27.5 kg/m
