What are the early warning signs of a heart attack?
It is important to recognize that many people who have had heart attacks had no warning signs at all. This especially concerns people who have diabetes where upwards of 50% percent of heart attacks were not recognized or were not associated with any warning signs. If there are warning signs, they include the following sensations: episodes of chest discomfort, often a squeezing sensation in the center of the chest, sometimes the discomfort is felt in the left arm, especially radiating towards the 5th finger. There can also be numbness in the arm. There can be associated nausea, shortness of breath, dizziness, sweating or loss of energy.
