Hi , you are just 24. Y are you worried for a heart attack. Being cautious is good , being worried is bad. If you have strong family history of heart attack, deranged lipid profile, diabetes and hypertension then adopt a good lifestyle and food habit from this age. Most common precipitating factors for cardiac disease is stress, overthinking, bad daily schedules, poor food choice, sedentary lifestyle, lack of motivation and lack of exercise.

No think about heart attack won't cause heart attack. Get an ECG and Echocardiogram.
