Insights
Severe uncontrolled hypertension is common in Jamaican specialist practices. Patients often have cardiovascular symptoms and require multiple medications for blood pressure control.
Area of Science:
- Cardiology
- Public Health
- Internal Medicine
Background:
- Severe uncontrolled hypertension (Grade III) poses a significant health challenge.
- Understanding patient characteristics and treatment outcomes is crucial for effective management.
- Jamaican specialist practices provide a unique setting to study hypertension prevalence and control.
Purpose of the Study:
- To characterize patients with severe uncontrolled hypertension in a Jamaican specialist practice.
- To assess blood pressure control levels achieved in routine clinical practice.
- To determine the number and types of antihypertensive medications needed for control.
Main Methods:
- Retrospective analysis of 500 consecutive patient records from January to December 2000.
- Data extraction focused on 48 patients diagnosed with severe (Grade III) hypertension (WHO/ISH criteria).
- Analysis included patient demographics, comorbidities, symptoms, blood pressure control, and medication regimens.
Main Results:
- 19% (48/500) of patients presented with severe Grade III hypertension.
- Patients were predominantly of African ethnicity, overweight/obese, and often had comorbidities like diabetes and congestive heart failure.
- Over half had blood pressure > 140/90 mm Hg; most required four or more antihypertensive drugs, with ACE inhibitors, diuretics, beta-blockers, and calcium channel blockers being most common.
Conclusions:
- Severe hypertension is a prevalent issue in Jamaican specialist private practices.
- Patients frequently exhibit cardiovascular symptoms, dyslipidemia, and necessitate polypharmacy for long-term blood pressure management.
- The findings highlight the need for intensified hypertension management strategies in this population.
Objective:
To determine the characteristics of patients with severe uncontrolled hypertension, in a Jamaican specialist practice; the level of blood pressure control achieved in routine clinical practice, and the number/type of antihypertensive medications required for blood pressure control.
Design:
This was a retrospective analysis of the medical records of 500 consecutive patients presenting to a consultant physician private group-practice between January and December 2000. Data were extracted from the records of the 48 patients with severe (Grade III) hypertension (WHO/ISH).
Results:
Fifty per cent (252) werefound to be hypertensive, 19% (48) had Grade III hypertension. The patients with severe uncontrolled hypertension were of mixed ethnicity, predominantly African. Most were less than 65 years old, never smoked cigarettes and were overweight/obese. Nearly one-half had LDL cholesterol >3.4 mg/dL. Diabetes (31%) and congestive heart failure (21%) were the most common comorbid conditions. Fifteen per cent had no illnesses other than severe hypertension. Cardiovascular symptoms were predominant, followed by dizziness. Only 19% of patients were asymptomatic. More than half of the patients achieved blood pressure > 140/90 mm Hg during the study period. Most patients received four drugs and the number of drugs prescribed increased with duration of follow-up. The antihypertensive medications most prescribed at one year were--angiotensin converting enzyme inhibitors (87%), diuretics (78%), calcium channel blockers (63%) and beta-blockers (69%).
Conclusion:
Severe hypertension was a common problem in the specialist private practice in Jamaica. Most patients had cardiovascular symptoms, were dyslipidaemic and required four or more antihypertensive drugs for adequate long-term control.
