Insights
Cerebral infarction is the most common type of stroke, affecting 72% of patients. Hypertension is the primary risk factor identified in stroke cases.
Area of Science:
- Neurology
- Cardiovascular Medicine
- Epidemiology
Background:
- Stroke is a sudden loss of brain function due to vascular issues.
- Understanding the prevalence of stroke subtypes and their risk factors is crucial for public health.
- This study investigated the frequency of cerebral infarction and hemorrhage in stroke patients.
Purpose of the Study:
- To determine the frequency of cerebral infarction and cerebral hemorrhage in a cohort of 100 stroke patients.
- To identify the most common type of stroke within the study population.
- To assess the prevalence of key risk factors associated with stroke.
Main Methods:
- A consecutive sampling technique was employed to recruit 100 stroke patients.
- Data collection included detailed patient histories covering hypertension, diabetes, smoking, and prior cardiovascular events.
- Blood pressure was measured upon admission and 24 hours later.
Main Results:
- Cerebral infarction occurred in 72% of patients, while cerebral hemorrhage was observed in 28%.
- Hypertension was identified as the most prevalent risk factor.
- The average blood pressure recorded was 180/100 mmHg.
Conclusions:
- Cerebral infarction is the predominant form of stroke.
- Hypertension stands out as the leading risk factor contributing to stroke incidence.
Background:
Stroke is rapidly developing phenomena of symptoms and signs of focal, and at times global, loss of cerebral function with no apparent cause other than that of vascular origin. The objective was to know the frequency of cerebral infarction and haemorrhage in one hundred patients of stroke in a period of one year.
Methods:
Data was collected by consecutive sampling technique. Total one hundred patients of stroke were collected for the study. They were assessed through a detailed history of hypertension, diabetes mellitus, smoking, previous stroke, transient ischemic attack (TIA), previous myocardial infarction, angina, atrial fibrillation, alcohol intake, drugs used for hypertension/diabetes mellitus. Blood pressure was recorded at arrival and 24 hours after admission.
Results:
There were 70% males and 30% females. Twenty percent of the patients were in the age range of 51-60 years, 26% of the patients were in the age range of 61-70 years and 18% were in the age range of 71-80 years. Cerebral infarction was present in 72% patients while cerebral haemorrhage was present in 28% patients. Hypertension was the most common risk factor among these stroke patients. Average blood pressure was 180/100 mmHg.
Conclusion:
Cerebral infarction is the commonest form of stroke. Hypertension is the leading risk factor in stroke patients.
