A prevalence of elevated ARR in rural Selangor

Abstract The objective of this study was to determine the prevalence of elevated Aldosterone Renin Ratio (ARR) in Rural Selangor. Methods This was a cross sectional study involving subjects in Kuala Selangor and Tanjung Karang. The World Health Survey Kish tables were used to select eligible subjects (≥18 years old) from each household. Their social demography, past medical history, anthropometric measurement and blood pressure were recorded. Blood were withdrawn for Aldosterone (ALD), Plasma Renin Activity (PRA), Creatinine (creat) and potassium (K). Raised ARR is defined as aldosterone/renin ratio of more than 20. Results A total of 392 subjects (age 55 +/- 14.1) were enrolled. Fourty three (11%) subjects showed an ARR > 20. Out of those with raised ARR, 16 (38%) were hypertensive, 2 of which were not taking any anti-hypertensive drugs and 27 subjects (62.8%) were normotensive. Only 2 (4.7%) of them were hypokalemic, one of them being hypertensive. Conclusion The prevalence of raised ARR in Rural Selangor was 11%, and only 4.7% of them were hypokalemic

Prevalence, awareness and control of hypertension in rural areas in Selangor and Perak

Abstract The aim of this study was to describe the prevalence, awareness and control of hypertension in the rural population of Perak and Selangor. Methods This was a population based cross-sectional study involving subjects in Kuala Selangor, Tanjung Karang and Bidor. The World Health Survey Kish tables were used to select eligible subject (≥18 years old) from each selected household. A Case Report Form (CRF) was used to record their social demography, past medical history, anthropometry measurement and blood pressure (BP). Hypertension was defined as a blood pressure > 140/90 mmHg. Hypertension controlled was defined as a blood pressure of < 140/90 mmHg. Results A total of 761 people participated in this study. Of which 287 (37.8%) were males and 473 (62.2%) were females. Out of this, 271 (35.6%) were hypertensive. The study showed 36 (4.7%) subjects were not aware that they have hypertension. Only 76% of hypertensive subjects were on HPT medication. One hundred and five (51%) subjects were on monotherapy, 66 (32%) were on dual therapy, 27 (13.1%) on triple therapy, 8 (3.9%) were on more than 3 medications. 73 (26.9%) of the hypertensive subjects were not on any HPT medications having a SBP of 133.9 +/- 17 and DBP of 86.2 +/- 49.3

Prevalence of elevated aldosterone renin ratio in three main states of Peninsular Malaysia

Objective: The objective of this study was to determine the prevalence of increased Aldosterone Renin Ratio (ARR) in parts of Selangor, Perak and Pahang. Methods: This was a cross sectional study involving subjects in Selangor, Perak and Pahang. The World Health Survey Kish tables were used to select eligible subjects (≥18 years old) from each household. Their social demography, past medical history, anthropometric measurement and blood pressure were recorded. Blood were withdrawn for Aldosterone (ALD), Plasma Renin Activity (PRA), Creatinine (creat) and potassium (K). Raised ARR is defined as aldosterone/renin ratio of more than 20. Results: A total of 1073 subjects (age 50 +/- 16.4). One hundred and nineteen (11.1%) subjects showed an ARR =/> 20. Forty nine (41.2%) out of the elevated ARR =/> 20 were hypertensive, 11 of which were not taking any anti-hypertensive drugs and 54 subjects (45.4%) were normotensive. Only 7 (5.9%) of them were hypokalemic, one of them being hypertensive. The main clinical characteristics of subjects with raised ARR are shown in Table 1. Conclusion: The prevalence of raised ARR in Rural Selangor was 11.1%, and only 5.9% of them were hypokalemic
