The actor did not disclose the reason he ended up at the hospital, but we can assume that he might have suffered from angina. According to the Cleveland Clinic, angina is one of the most common cardiac cause of chest pains among athletes 35 and older.
Angina is caused by reduced blood flow to the heart muscle as a result of coronary artery disease. The pain usually comes when a person exercises and it goes away by getting some rest.
It’s safe to say that whenever anyone experiences chest pains, don’t hesitate to seek immediate attention. Take Banderas for example, more than likely he had never experienced pain like this before which is why he did the right thing by calling an ambulance and got the medical attention that he needed.
