my grandmother has had 3 heart attacks, still living, my mother had one at 49 which killed her. She however smoked, had a poor diet and was something of an angry person! I am female have now just turned 40, have bmi of 32 not sure how fit (can jog a mile slowish, cycle 30-40 miles slow to med intensity although i dont do these regular). Smoked for 22 years, gave up for 5 yrs. What are my chances of a heart attack? Im sure past cholesterol readings have been within normal range.
