Objective: To determine the potential risk factors in patients aged under 40 years with a positive Exercise Tolerance Test (ETT).
Study Design: Prospective study.
Place and Duration of Study: The study was carried out at the Department of Cardiology Choudhary Pervaiz Elahi Institute of Cardiology (CPEIC), Multan, Pakistan, from 1st January 2021 to 1st March 2022.
Materials and Methods: The study included 285 patients with positive ETT, selected through non-probability consecutive sampling. Patients were grouped into two age brackets: 20-30 and 31-40.  Patients were advised to stop taking nitrates, calcium channel blockers and beta blockers a day before the test.  The patients were investigated for potential risk factors that caused the positivity of EET.
Results The study was conducted on 285 patients.  The age of the participants was 30.12±5.64 years. There were 185 (64.9%) males and 100 (35.1%) females. The BMI was .32±1.38 kg/m2. Obesity was recorded in 38 (13.3%) patients, 85 (29.8%) had a family history, 63 (22.1%) had dyslipidemia, hypertension in 58 (20.4%), 32 (11.2%) had a smoking history, and 56 (19.6%) had diabetes mellitus. Diabetes Mellitus (p=0.00) and dyslipidemia (p=0.004) were found to be the most significant risk factors in patients aged between 31-40 years with positive EET.
Conclusion: Diabetes mellitus and dyslipidemia are the most significant causes of positive EET in patients aged between 31-40 years.
