Insights
Coronary artery disease (CAD) affects more men than women, typically over 30. Exercise stress tests help stratify risk, with most affected patients falling into intermediate or low-risk categories.
Area of Science:
- Cardiology
- Preventive Medicine
- Diagnostic Testing
Background:
- Coronary artery disease (CAD) is a leading cause of death and disability.
- CAD presents as chronic stable angina or acute coronary syndromes (ACS), including unstable angina (UA), NSTEMI, and STEMI.
Purpose of the Study:
- To describe the risk stratification and prognosis of CAD in Yemeni patients.
- To analyze outcomes of exercise stress testing in a Yemeni population.
Main Methods:
- Retrospective descriptive study of 302 patients.
- Exercise stress testing conducted using the Bruce protocol on a treadmill (TMT).
Main Results:
- The study included 302 patients, with a mean age of 43.29 years (range 22-70); 79.80% were male.
- Of the patients, 86.75% had normal stress test results.
- Among affected patients (13.25%), 82.50% were male, all over 30 years old, predominantly over 50. 45% of positive tests were high-risk, while 55% were intermediate/low-risk.
Conclusions:
- CAD impacts males more frequently than females.
- The condition affects individuals over 30, with a higher prevalence in older patients.
- Most diagnosed CAD patients were categorized into high, intermediate, and low-risk groups, with rare occurrences in the very high-risk category.
Background:
Coronary artery disease (CAD) is a common medical problem that remains a great cause of morbidity and mortality. Based on clinical manifestation, CAD span from chronic stable angina to acute coronary syndrome (ACS), which encompasses (1) unstable angina (UA), (2) non-ST-elevation myocardial infarction (NSTEMI), and (3) ST-elevation myocardial infarction (STEMI).
Objective:
This study was conducted to describe the risk stratification and prognosis of CAD in Yemeni patients undergoing an exercise stress test.
Method:
A retrospective descriptive study involved the records of 302 patients who undergoing exercise stress testing by the Bruce protocol of Treadmill (TMT).
Results:
Out of 302 patients, the mean age was 43.29 years, (range, 22-70 years), and 79.80% were males. The majority of patients (86.75%) were normal. Most of the affected patients (82.50%) were males. All of the affected peoples were more than 30 years old with predominance in more than 50 years old. Results showed that 45% of the positive (+ve) patients were in high-risk group, and 55% were in intermediate and low-risk groups.
Conclusions:
CAD affects males more than females. It affects patients older than 30 years and predominates in elderly patients. Most of the affected patients were in the high, intermediate, and low-risk groups and rarely were in the very high-risk group.

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
