Yes, too much cocaine use can increase the risk of heart attacks. Cocaine is a stimulant drug that can cause constriction of blood vessels and increase blood pressure, which can lead to a heart attack or other cardiovascular complications, especially in individuals with pre-existing heart conditions. Additionally, cocaine can cause irregular heartbeats, which can also lead to cardiac arrest or heart attack. It is important to seek medical attention immediately if someone experiences chest pain, shortness of breath, or any other signs of a heart attack after cocaine use.
