Pain, discomfort, and pressure in the chest are the most common symptoms of heart attack in men. These can include a sensation of fullness or squeezing in the chest. These symptoms are sometimes accompanied by pain in one or both arms, the jaw, back, stomach, or neck. While women are more likely than men to experience symptoms other than the characteristic chest pain and pressure, men can also experience other types of symptoms or mistake a heart attack for another condition, such as gastroesophageal reflux. Other signs and symptoms of heart attack include

shortness of breath,
nausea,
vomiting,
fatigue,
lightheadedness,
fainting,
dizziness,
pressure in the upper back, and
a feeling of breaking out in a cold sweat.

Causes of heart attacks in men

Heart attacks are caused when there is an inadequate supply of oxygen-carrying blood to the muscle of the heart. A heart attack is medically known as a myocardial infarction. Blockage of a coronary artery by a blood clot and/or atherosclerotic plaque (from coronary artery disease) is the most common cause for the interruption in blood flow to the heart muscle.
