not neccessarily but the risk is significantly higher. When suffering from heart attack at such an early stage, there is very likely a significant risk factor involved, like: 1. high cholesterol, 2. smoking, 3. diabetes, 4. high blood pressure, 5. overweight or obesity, 6. extremely low exercise level, or the two of which you cannot influence which are 7. family history of premature heart disease and 8. being male. (the risk factor are in arranged in descending importance). All one can do is limit the risk factors you can do something about, take the meds and you can still be knocked off at zebra crossing at the are of 92. All the best!
