In addition to calling for help, what is essential for someone suspected of having a heart attack?

Keeping someone suspected of having a heart attack upright and calm is crucial because it can help maintain blood flow and reduce strain on the heart. When a person is upright, it may alleviate pressure on the heart and improve breathing. Additionally, staying calm is essential as anxiety can increase heart rate and oxygen demand, further stressing the heart.

Encouraging movement, such as making someone move around, can exacerbate their condition by increasing heart workload, while asking them to eat can introduce further complications, especially if surgical intervention is needed later. Providing a blanket is not a primary concern in emergency situations regarding heart attacks compared to ensuring the person remains calm and in a stable position.
