I'm a bit worried about heart health and wanted to ask. What are some early signs I should watch out for that might suggest a heart attack? And how long do those symptoms usually last before it gets serious? Also, I've heard about angina and heart attacks, but I'm not quite sure how they're different. Could you explain that for me?

Angina is the heart pain, heart attack means there is ischaemia to the heart, jaw pain,shoulder pain and chest pain along with sweating and pailpitations are commonly seen in the patients.
