The duration of a silent heart attack can vary. If symptoms do present, a person should seek medical attention immediately. When blood flow to the heart stops for around 15 minutes, the heart can become damaged. After about 30 minutes, the damage is irreversible.
People often don't know they've had a silent heart attack until weeks or months later when a healthcare provider finds heart damage. Missing signs or symptoms normally unrelated to a heart attack can make it tricky to identify a silent heart attack. But it still causes damage like any other heart attack.
Imaging tests, such as an electrocardiogram or echocardiogram, are the only way to identify a silent heart attack. If you think that you've had a silent heart attack, talk to your health care provider. A review of your symptoms and health history and a physical exam can help your provider decide if you need more tests.
Over 50% of heart attacks have "beginning" symptoms that may come and go for days or weeks.
Because silent heart attacks may go unnoticed, they can cause a significant amount of damage. And without treatment, they can be deadly.
The people who are most vulnerable to silent heart attacks fall into one of three categories: women, people with diabetes and people who are elderly. "The reason these groups are most at risk is because they don't present with the tell-tale symptom of severe, pounding chest pain," Dr. Kazziha says.
Normally, silent heart attacks are found long after the heart attack is over. Treatment will mostly involve taking medicines. These medicines help improve blood flow to your heart, prevent clotting, and reduce the risks of having another heart attack.
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.)
How long can a heart attack last? Heart attack symptoms typically persist for longer than a few minutes. They may go away and come back again, or they may occur intermittently over several hours .
Heartburn, angina and heart attack may feel very much alike. Even experienced doctors can't always tell the difference from your medical history and a physical exam. That's why, if you go to the emergency room because of chest pain, you'll immediately have tests to rule out a heart attack.
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.
Most heart attacks involve discomfort in the center or left side of the chest that lasts for more than a few minutes or that goes away and comes back. The discomfort can feel like uncomfortable pressure, squeezing, fullness, or pain. Feeling weak, light-headed, or faint. You may also break out into a cold sweat.
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.
A silent heart attack, also called a silent Ischemia, is a heart attack that has either no symptoms, minimal symptoms or unrecognized symptoms. A heart attack is not always as obvious as pain in your chest, shortness of breath and cold sweats.
Electrocardiogram. An electrocardiogram (ECG) is an important test in suspected heart attacks. It should be done within 10 minutes of being admitted to hospital. An ECG measures the electrical activity of your heart.
Common heart attack symptoms include: Chest pain that may feel like pressure, tightness, pain, squeezing or aching. Pain or discomfort that spreads to the shoulder, arm, back, neck, jaw, teeth or sometimes the upper belly. Cold sweat.
Catch the signs early
Pay attention to your body and call 911 if you experience: Chest discomfort. Most heart attacks involve discomfort in the center of the chest that lasts more than a few minutes – or it may go away and then return. It can feel like uncomfortable pressure, squeezing, fullness or pain.
However, people who have had a silent heart attack may be at risk of other complications, such as heart failure and stroke. According to a 2018 study, a person who has had a silent heart attack has an estimated 35% increased risk of heart failure. People in their early 50s or younger have an even greater risk increase.
Sudden stress can cause a cardiac event that feels like a heart attack, called takotsubo cardiomyopathy or “broken heart syndrome.” This stress-induced cardiomyopathy isn't associated with the artery blockages that lead to a heart attack, though it may cause your heart to pump inefficiently for up to a month.
Chawla says. “People ignore symptoms, which are usually taking place for weeks or months before finally having a heart attack with complete blockage. At that point, the heart isn't getting blood and it can go into a life threatening rhythm, which presents as cardiac arrest.”
A heart attack may last for two to five minutes, while a full heart attack can last for more than 20 minutes. A heart attack (also called myocardial infarction or MI) happens when blood flow from the coronary arteries to the heart is reduced or blocked completely.
Dr. Xu says the majority of patients experience somewhat typical symptoms, such as radiating chest pain, heaviness or discomfort, heart palpitations, cold sweats, and shortness of breath.
The most typical symptoms, which are likely to affect both men and women, are nausea with an empty or full stomach, feeling bloated, or having an upset stomach. Periodically diminishing and then returning for a brief period, abdominal symptom before a heart attack is episodic.
Those with an anxiety disorder have most likely experienced a panic or anxiety attack at some point in their lives. The symptoms can closely mimic heart attacks for some people—they may feel chest pain, shortness of breath and heart palpitations, or a racing heartbeat.
