Evaluation of hypertension and other risk factors in ischemic heart disease
1Institute of Cardiovascular Diseases, Dhaka, Bangladesh.
Insights
Hypertension, smoking, and high cholesterol are key risk factors for ischemic heart disease (IHD) in Bangladesh. This study highlights these factors in 100 IHD patients, emphasizing their critical role in disease development.
Area of Science:
- Cardiology
- Epidemiology
- Public Health
Background:
- Ischemic heart disease (IHD) poses a significant health burden globally and in Bangladesh.
- Understanding the specific risk factors prevalent in the Bangladeshi population is crucial for targeted prevention strategies.
Purpose of the Study:
- To investigate the role of hypertension as a primary risk factor for IHD.
- To identify other significant cofactors, including smoking and hyperlipidemia, contributing to IHD in Bangladesh.
Main Methods:
- A case series of 100 patients diagnosed with IHD for the first time was analyzed.
- Data collected included patient demographics, blood pressure, smoking status, serum cholesterol, and triglyceride levels.
- Comparisons were made with a control group of 50 healthy individuals.
Main Results:
- Hypertension was identified in 31% of IHD cases, with elevated blood pressure readings.
- A high prevalence of smoking (74%) was observed among IHD patients.
- Significantly higher mean serum cholesterol (6.48 +/- 1.66 mmol/L) and triglyceride levels were found in IHD patients compared to controls.
Conclusions:
- Hypertension, smoking, and hyperlipidemia are identified as the most significant risk factors for IHD in the Bangladeshi population.
- These findings underscore the importance of managing these modifiable risk factors to reduce the incidence of IHD.
Abstract:
The author presented data obtained in Bangladesh, to elucidate the role of hypertension as a risk factor along with others such as smoking, cholesterol and diabetes mellitus as cofactors in ischaemic heart disease (IHD). There was a series of 100 cases with IHD admitted within 12 hours after the onset of chest pain observed in this study. They all were diagnosed as IHD for the first time. Of them, 94 were male and 6 female, with an age range of 25-77 years (mean 50.16 +/- 14 years). On grouping of IHD, 21 had angina pectoris and 79 acute myocardial infarction. 31% cases of IHD had hypertension. The blood pressure ranged between 168.54 +/- 24.85 and 106.29 +/- 16-80 mmHg. 74 out of the 100 cases with IHD were smokers. The mean value of serum cholesterol in this series was 6.48 +/- 1.66 mmol/L and that among 50 normal controls was 4.76 +/- 1.28 mmol/L (P < 0.01). The serum triglyceride determinations between the 94 cases of IHD and 50 normal controls showed values with statistically significant difference. The author concluded in this study that, hypertension, smoking and hyperlipidemia are the most important risk factor of IHD in Bangladesh.
