What time of day is a heart attack most likely to happen? “Most heart attacks hit during the early morning hours from 4 – 10 am when blood platelets are stickier, and there is increased adrenaline released from the adrenal glands that can trigger rupture of plaques in coronary arteries,” said Dr. Goodroe.
But the last stage of sleep — REM, or rapid eye movement, sleep [when we believe most dreaming occurs] — is a risk period for cardiovascular emergencies because when you dream, you have a dramatic increase of activity of the autonomic nervous system — even more than when you are awake.
Both panic attacks and heart attacks can wake you from sleep.
Less often, a coronary artery spasm can cut off your blood flow. Heart attacks can happen when you're asleep or awake.
Sleeping more than seven or less than six hours a night has been linked to a higher risk of a heart attack or stroke, according to new research.

Age. The majority of heart attack deaths occur in patients ages 65 and older, but a man's risk begins to increase at 45 (for women, it starts at 55).
A heart attack may strike suddenly, but most people have warning signs and symptoms hours, days or weeks beforehand. One of the earliest warning signs of an impending heart attack is chest pain, or angina, that occurs repeatedly because of exertion and is then eased by rest.
Pre-Heart Attack Symptoms – Female
Men may feel pain and numbness in the left arm or the side of the chest. In women, these symptoms may appear on the right side. Women may experience unexplained exhaustion, or feel drained, dizzy or nauseous. Women may feel upper back pain that travels up into their jaw.
SMI warning signs
It can feel like an uncomfortable pressure, squeezing, or pain. Discomfort in other upper-body areas, such as one or both arms, the back, the neck, the jaw, or the stomach. Shortness of breath before or during chest discomfort. Breaking out in a cold sweat, or feeling nauseated or lightheaded.
Signs of a heart attack include:
- Pain or discomfort in one or both arms, the back, neck, jaw or stomach. - Shortness of breath with or without chest discomfort. - Other signs such as breaking out in a cold sweat, nausea or lightheadedness. (If you're experiencing any of these symptoms, call 9-1-1 immediately.)
Others -- women more so than men -- will experience some atypical symptoms as well, which may include fatigue, a general sense of unease, vague discomfort, back or abdominal pain and declining stamina. Both types of symptoms can be experienced months before an actual heart attack occurs.
One lung problem, pulmonary embolism, can mimic a heart attack and is equally serious. A pulmonary embolism is a blood clot in an artery in the lungs. This clot cuts off blood flow, and the lung tissue begins to die. A pulmonary embolism is a life-threatening medical emergency that requires immediate treatment.
Using the toilet
If your heart function is already compromised, this could be a trigger for sudden cardiac arrest. Going to the bathroom can also trigger something called a vasovagal response. Using the bathroom puts pressure on the vagus nerve, which can sometimes slow your heart rate.
Sleeping on your right side may be the best option for people with heart failure. Although some people think sleeping on your right side could restrict blood flow back to the heart, there's not enough evidence to prove that it's harmful.
A silent heart attack is a heart attack that has few, if any, symptoms or has symptoms not recognized as a heart attack. A silent heart attack might not cause chest pain or shortness of breath, which are typically associated with a heart attack.
Heart attack signs and symptoms in men and women: Chest pain or discomfort; Shortness of breath; Pain or discomfort in the jaw, neck, back, arm, or shoulder; Feeling nauseous, light-headed, or unusually tired.
“I understand that heart attacks have beginnings and on occasion, signs of an impending heart attack may include chest discomfort, shortness of breath, shoulder and/or arm pain and weakness. These may occur hours or weeks before the actual heart attack.
If Low Power Mode is turned on, you won't receive any high or low heart rate or irregular rhythm notifications. Learn more about Low Power Mode. Apple Watch cannot detect heart attacks. If you ever experience chest pain, pressure, tightness, or what you think is a heart attack, call emergency services immediately.
While no one particular heart rate qualifies as a heart attack, a rapid heart rate outside 60 to 100 beats per minute should be monitored closely. Doctors cannot say that a particular heart rate qualifies as a heart attack. Your heart rate is not a reliable indicator that you are having a heart attack.
Some heart attacks strike suddenly. But many people have warning signs and symptoms hours, days or weeks in advance. Chest pain or pressure (angina) that keeps happening and doesn't go away with rest may be an early warning sign. Angina is caused by a temporary decrease in blood flow to the heart.
How long heart attack symptoms occur. Mild heart attack symptoms might only occur for two to five minutes then stop with rest. A full heart attack with complete blockage lasts much longer, sometimes for more than 20 minutes.
Noninvasive tests help identify who's really at risk for a heart attack. Seemingly healthy people are “suddenly” having heart attacks because, as it turns out, their arteries are not perfectly healthy and they don't know it.
In a “mini” heart attack, blood flow to the heart is partially blocked. Symptoms include chest pain and are similar to those of a heart attack, but there is less damage to the heart. The technical term for a “mini” heart attack is a non-ST elevation myocardial infarction (NSTEMI).
Obesity, Unhealthy Diet, and Physical Inactivity. Compared to those at a normal weight, people with overweight or obesity are at increased risk of heart disease and stroke and their risk factors, including high blood pressure, high LDL cholesterol, low HDL cholesterol, high triglycerides, and type 2 diabetes.
