Why do heart attacks happen at night?

Answered by 1 Apollo Doctors

Researchers found that at around 6:30 a.m. the circadian system sends out an increased amount of PAI-1 cells which blocks blood clots from breaking down. The more PAI-1 cells in the blood, the higher the risk for a blood clot that leads to a heart attack

I'm really concerned because I've been experiencing skipped heartbeats for about five months now. It often feels like there's a pause in my heartbeat, maybe for a second, but I'm not completely sure. I've never fainted or felt dizzy when this happens, but it does make me feel very anxious. I'm really worried about the possibility of a sudden cardiac arrest because of these skipped beats. Are these skipped heartbeats something I should be seriously worried about, even though my ECG, ECHO, and HOLTER tests all came back normal?

Skip heartbeats can be concerning, but they are not always dangerous, especially if your tests (ECG, ECHO, HOLTER) have come back normal. It is important to manage your anxiety as stress can worsen the symptoms. In some cases, lifestyle changes such as reducing caffeine intake, managing stress, and getting enough sleep can help. If the symptoms persist or worsen, medications like beta-blockers (e.g. Metoprolol) can be prescribed to help regulate your heartbeat. However, it is important to follow up with your doctor for further evaluation and management.

I'm 22 years old and my weight is 112. I recently had an ECG done because I was feeling anxious, and it shows PACs with sinus rhythm. I'm really worried about what this means. Can you help me understand if everything's okay with my ECG?

Premature Atrial Contractions (PACs) with a sinus rhythm can be a common finding and are often benign, especially in younger individuals. They can occur due to stress, anxiety, caffeine, or other stimulants. Given that you were feeling anxiety at the time of the ECG, it is possible that this contributed to the PACs. However, it's important to discuss these findings with your healthcare provider to ensure there are no underlying issues and to get personalized advice. They may recommend further monitoring or lifestyle adjustments to help manage your symptoms.
