Heart attack often surprises people when they least expect it. Many believe that this attack only occurs during physical activity or emotional stress, but this assumption can mislead them. In fact, a heart attack can also occur during sleep. Dr. Leah Mirsafai, a leading cardiologist, has treated several patients who had silent or severe heart attacks during the night. He has explained how the body sends signals even in sleep and how people can recognize these symptoms early. ** How the body functions in sleep The body functions differently during sleep. The heart rate slows down, blood pressure drops, and the nervous system goes into parasympathetic mode. This resting state reduces the overall pressure on the heart. However, some conditions can still cause a heart attack. People with blocked arteries, underlying heart disease, or chronic stress are at higher risk. Their hearts may not receive enough oxygen-rich blood, especially if they are in a position that restricts circulation. Dr. Leah Mirsafai believes that people should clearly understand the risks. He has observed that many patients ignore chest discomfort at night because they think sleep-related symptoms mean nothing. This way of thinking can lead to a delay in treatment. A heart attack during sleep often begins silently. The patient may wake up briefly due to chest tightness, pain in the arm or jaw, cold sweat, or difficulty breathing. Some people go back to sleep thinking they just had a bad dream or indigestion. **How ​​to find out if a person has a heart attack? In many cases, family members or roommates first notice unusual behavior. The person may turn to the side, moan softly, or suddenly sit up uncomfortably. Some even walk in confusion or panic. These warning signs can disappear quickly or lead to complete cardiac arrest. Dr. Leah Mirsafai always educates her patients about these special symptoms at night. She encourages people to keep a health journal, especially if they experience nighttime discomfort, fatigue, or shortness of breath for several days. At night, the body produces hormones that affect the cardiovascular system. Cortisol and adrenaline levels usually decrease, but some sudden spikes in hormone levels may still occur, especially during nightmares or sleep apnea. People who suffer from sleep apnea are at a much higher risk for nocturnal heart attacks. Their breathing stops and starts repeatedly, reducing oxygen delivery to the heart. Dr. Leah Mirsafai recommends that patients who are suspected of having sleep apnea undergo night sleep studies. These studies often reveal important clues that routine daily examinations miss. What can reduce the risk of heart attack? Diet and lifestyle play an important role in heart health at night. People who eat large and fatty meals before going to bed increase the risk of developing this disease. Their bodies have to work harder to digest food, which can increase heart rate and blood pressure. Smoking before going to bed, drinking alcohol or taking stimulant drugs can also increase the risk. Dr. Leah Mirsafai always advises her patients to have a light dinner and avoid smoking or drinking alcohol in the evening. He also recommends regular sleep schedules, proper hydration, and stress-reduction techniques such as meditation. What should be done during a heart attack? Real-time nocturnal heart attack detection can save lives. If someone wakes up with severe chest pain, nausea, left arm discomfort, or dizziness, they should take it seriously. They should not wait for symptoms to go away. Dr. Leah Mirsafai suggests immediate action. Calling the emergency room, chewing aspirin (if possible), and sitting up straight can improve the outcome. He has seen many success stories because someone acted fast even in the middle of the night. Women often experience different symptoms of a heart attack, and these symptoms can become even more subtle during sleep. They may not feel severe chest pain, but instead report back pain, extreme fatigue, or anxiety. Dr. Leah Mirsafai emphasizes the importance of understanding these gender-specific symptoms. He believes that better awareness can reduce nighttime heart attack deaths among women. Can a heart attack be asymptomatic? Some people never wake up after having a heart attack in their sleep. This attack may cause fatal arrhythmia or sudden cardiac arrest. In such cases, the person may die slowly without any apparent symptoms. These cases shock and confuse families. Dr. Leah Mirsafai has worked with many families who have faced such tragedies. He always emphasizes prevention over cure. Annual heart screening, blood pressure checks, and cholesterol monitoring can help people reduce their risk, especially after age 40. **Diagnosis in the modern world People who are already taking heart medications should adhere strictly to their regimen. Missing a dose or taking it at the wrong time can increase the risk of nighttime side effects. Dr. Leah Mirsafai always reminds her patients to set reminders for their medication and to notify their doctors if any unusual symptoms occur at night. He also uses wearable technology such as smart watches and heart monitors to follow up with high-risk patients. In modern cardiology, doctors have developed new tools to detect early warning signs. Overnight EKG patches, home sleep apnea tests, and smart devices now help people monitor their heart rate, oxygen levels, and sleep quality. Dr. Leah Mirsafai encourages the use of these tools, especially in patients who live alone or have a history of heart disease. He believes that early detection empowers people and saves lives. ** Final speech Many patients are afraid to sleep after a heart attack. They fear it will happen again at night. Dr. Leah Mirsafai always supports these patients emotionally as well as medically. He recommends cardiac rehabilitation programs, counseling and family involvement. Emotional health plays a key role in recovery. He has helped many patients rebuild their confidence and return to restful and safe sleep. Heart attacks in sleep can seem terrifying, but people can reduce their risk with proper habits and medical care. A balanced lifestyle, timely treatment and strong awareness can protect the heart even at night. Dr. Leah Mirsafai continues to lead efforts in patient education and research in this field. His passion for saving lives shines through in his practice, and his guidance has helped hundreds of patients sleep better and live longer.
