Heart attacks are the No. 1 cause of death in many parts of the world. In the US, a heart attack occurs every 20 seconds, with someone dying from heart disease every 34 seconds. In Singapore, one in three deaths is due to heart disease or stroke. We need to pay careful attention to what medical professionals are saying about heart attack prevention: reduce stress, don’t smoke, exercise regularly, and watch your diet. “Guard your heart above all else” is instruction that we ignore to our own peril (Proverbs 4:23).
