Early Warning Symptomps of Heart Disease And What should you do?

Heart attack, or myocardial infarction, is the number one killer of both men and women in the U.S. Each year, about 1.1 million Americans suffer a heart attack, and 460,000 of these are fatal. Most of the deaths from heart attacks are caused by ventricular fibrillation of the heart that occurs before the victim of the heart attack can reach an emergency room. Those who reach the emergency room have an excellent prognosis; survival from a heart attack with modern treatment should exceed 90%. The 1% to 10% of heart attack victims who die later include those victims who suffer major damage to the heart muscle initially or who suffer additional damage at a later time.

Procedures such as coronary angiogram and PTCA (coronary balloon angioplasty), and clot dissolving drugs are available that can quickly open blocked arteries in order to restore circulation to the heart and limit heart muscle damage. In order to optimally benefit heart attack victims and limit the extent of heart damage, these treatments to open blocked arteries should be given early during a heart attack. Blood pressure is not a reliable measurement of whether one is having a heart attack. Blood pressure during a heart attack can be low, normal, or elevated.

Cardiac arrest vs. heart attack

Sometimes there is confusion between the terms “cardiac arrest” and “heart attack.” A heart attack, or myocardial infarction, is damage to the heart muscle that occurs due to reduced blood flow to the heart muscle, depriving the heart muscle of the oxygen it needs to function properly. Cardiac arrest means that the heart stops beating and death is imminent. A heart attack, if severe, can lead to cardiac arrest, and this is what occurs when a heart attack is fatal. However, other conditions, such as serious arrhythmias or shock, can also cause cardiac arrest.
