Heart-attack or cardiac arrest ?

A cardiac arrest, also known as cardiopulmonary arrest or circulatory arrest, is the abrupt cessation of normal circulation of the blood due to failure of the heart to contract effectively during systole.^[1]
A cardiac arrest is different from (but may be caused by) a heart attack or myocardial infarction, where blood flow to the still-beating heart is interrupted (as in cardiogenic shock).
"Arrested" blood circulation prevents delivery of oxygen to all parts of the body. Cerebral hypoxia, or lack of oxygen supply to the brain, causes victims to lose consciousness and to stop normal breathing, although agonal breathing may still occur. Brain injury is likely if cardiac arrest is untreated for more than five minutes,^[2] although new treatments such as induced hypothermia have begun to extend this time.^[3][4] To improve survival and neurological recovery immediate response is paramount.^[5]
Cardiac arrest is a medical emergency that, in certain groups of patients, is potentially reversible if treated early enough (See "reversible causes" below). When unexpected cardiac arrest leads to death this is called sudden cardiac death (SCD).^[1] The primary first-aid treatment for cardiac arrest is cardiopulmonary resuscitation (commonly known as CPR) which provides circulatory support until availability of definitive medical treatment, which will vary dependent on the rhythm the heart is exhibiting, but often requires defibrillation.

The chances you get hit by an attack increase when you: smoke, drink alcohol, have overweight, have a wrong diet, (at that moment diabetes sees an opportunity to join the party). Of course there are many more factors that cause you to get a bad health. Air pollution, bad mood, stress, private circumstances, work etc.

Be aware it's not just the heart that will be affected. Liver, pancreas, lungs, intestines, kidneys and all the other organs and glands will receive their share.....

A smile, a laughter, love, peace, sports and correct food just might get you on the right side of the line and prevent you to get ill.
It's great to see someone smile, it's even better to hear them laught. What's wrong with loving eachother instead of hating.... Then peace will be the result. Sports will keep you moving and I tell you: it's no punishment to eat the right fruits and foods.
Cayenne peppers have proven to be very effective, and there are more remedies to benefite your heart.

Often diabetes patients believe they suffered a heartattack but were the symptoms caused by a Hypo.

Hypoglecemia causes symptoms similar to those of an anxiety attack:
sweating, nervousness, shaking, faintness, palpitations, and hunger. More severe hypoglycemia reduces the sugar supply to the brain, causing dizziness, fatigue, weakness, headaches, inability to concentrate, confusion, inappropriate behavior that can be mistaken for drunkenness, slurred speech, blurred vision, seizures, and coma. Severe and prolonged hypoglycemia may permanently damage the brain.

Symptoms can begin slowly or suddenly, progressing from mild discomfort to severe confusion or panic within minutes. Sometimes, people who have had diabetes for many years (especially if tightly controlled) are no longer able to sense the early symptoms of hypoglycemia, and faintness or even coma may develop without any other warning.
