If you’re confused by the terms used to describe heart attacks, you’re not alone. They’re often described as “mild” or “massive,” or even the ominous-sounding “widow maker.” But these terms are not necessarily helpful, and they may create confusion and anxiety.
The good news: most people who have a heart attack survive. The bad news? “Any heart attack can be fatal, no matter how big, how small, or where it occurs in the heart,” says Dr. James Januzzi, a cardiologist at Harvard-affiliated Massachusetts General Hospital. “Furthermore, there’s a lot of misunderstanding among the general public about what a heart attack actually is,” he says.
The connection between heart attack vs. cardiac arrest
Perhaps the most common source of confusion is the difference between a heart attack and cardiac arrest. A heart attack (what doctors call a myocardial infarction or MI) is defined as damage to part of the heart muscle caused by inadequate blood flow to that area. Most of the time, this happens due to a blockage in one of the heart’s arteries. Known as a type 1 heart attack, such blockages typically occur when cholesterol-laden plaque lining an artery ruptures. A clot forms, obstructing the vessel.
While a heart attack is a plumbing problem, a cardiac arrest is an electrical problem. Cardiac arrest happens when the heart’s electrical system malfunctions, causing it to beat rapidly and chaotically — or to stop beating altogether. Without blood circulating to the brain, lungs, and other organs, the person gasps or stops breathing and becomes unresponsive within seconds.
A heart attack is a common cause of cardiac arrest, but most heart attacks do not lead to cardiac arrest. Other possible causes of cardiac arrest include heart failure, a clot in the lungs, a serious imbalance of potassium, magnesium, or other minerals in the blood, a drug overdose, or a blow to the chest.
Does size matter?
Some heart attacks cause more harm than others. During a heart attack, blood levels of a protein released by damaged muscle (troponin) give some sense of severity. Afterwards, an ultrasound of the heart (echocardiogram) can reveal the extent of the damage. “A large heart attack will significantly reduce the squeezing strength of the heart muscle,” says Dr. Januzzi.
The term “widow maker” refers to a heart attack caused by a blockage near the top of the left anterior descending (LAD) artery, the main artery that supplies blood to the front of the heart. However, heart attacks that involve the LAD are not necessarily fatal, and those involving other arteries can be deadly, too.
What to do
Call 911 right away if you or someone near you has symptoms of a heart attack or cardiac arrest. Common heart attack symptoms include:
- uncomfortable pressure, squeezing, or pain in the chest
- pain or other uncomfortable sensations in an arm, the back, neck, jaw, or stomach
- shortness of breath
- sudden nausea or vomiting
- lightheadedness or dizziness
- unusual fatigue.
Bible verses for today’s meditation and inspiration: Matthew E. McLaren
Psalm 10:3-4 For the wicked boasts of his heart’s desire, And the greedy man curses and spurns the LORD. The wicked, in the haughtiness of his countenance, does not seek Him All his thoughts are, “There is no God.”
Isaiah 10:15-16 Is the axe to boast itself over the one who chops with it? Is the saw to exalt itself over the one who wields it? That would be like a club wielding those who lift it, Or like a rod lifting him who is not wood. Therefore the Lord, the GOD of hosts, will send a wasting disease among his stout warriors; And under his glory a fire will be kindled like a burning flame.

Deuteronomy 8:11-17 “Beware that you do not forget the LORD your God by not keeping His commandments and His ordinances and His statutes which I am commanding you today; otherwise, when you have eaten and are satisfied, and have built good houses and lived in them, and when your herds and your flocks multiply, and your silver and gold multiply, and all that you have multiplies,
Judges 3:7 The sons of Israel did what was evil in the sight of the LORD, and forgot the LORD their God and served the Baals and the Asheroth.
Judges 8:33-34 Then it came about, as soon as Gideon was dead, that the sons of Israel again played the harlot with the Baals, and made Baal-berith their god. Thus the sons of Israel did not remember the LORD their God, who had delivered them from the hands of all their enemies on every side;
