- Target blood pressure attainment in diabetic hypertensive patients: need for more diuretics?
- Published at:Int J Clin Pharmacol Ther. 2009 Jul;47(7):434-8.
OBJECTIVE: To determine target blood pressure attainment and to evaluate blood pressure control relative to type of therapy among diabetic hypertensive patients. METHODOLOGY: An observational retrospective study of all diabetic hypertensive patients visiting Al-Watani governmental medical center from August 01, 2006 until August 01, 2007. The blood pressure (BP) measurement made during the patient\'s recent visit and documented in the medical files was used in the study. Controlled BP values for hypertensive patients with diabetes mellitus were defined per JNC 7 guidelines: 130/80 mmHg or lower. Proportions of use of 5 different antihypertensive drug classes were compared between patients with controlled and uncontrolled BP. RESULTS: Of the 311 patients, 79 (25.4%) had their BP controlled. No significant differences in age, gender, body weight, duration of hypertension or diabetes, renal function, average number of anti-hypertensive medications and doses of most commonly reported antihypertensive medications were found between controlled and uncontrolled BP groups. ACE-I/ARB was the most commonly used drug class in both groups. Overall, the use of ACE-I/ARB, beta-blockers, calcium channel blockers, alpha-blockers and multi drug regimens were also not significantly different between the controlled and uncontrolled groups. However, overall use of diuretics was significantly higher in controlled group than uncontrolled group (59.5% versus 45.7%, p < 0.001). CONCLUSION: Despite the common use of ACE-I/ ARB as recommended per JNC 7th report, the majority of the patients had uncontrolled BP. Diuretics is an important drug class in attaining target BP. Use of diuretics in combination with ACE-I as well as drug compliance needs to be emphasized and encouraged.
