To determine if your heart condition is normal or if you need an angiography, a cardiologist must first evaluate your symptomssuch as chest pain or shortness of breathand review non-invasive tests like an ECG, echocardiogram, or stress test. An angiography is an invasive procedure, not a routine test. It is typically recommended only if your initial test results suggest significant arterial blockages, or if you are experiencing unstable angina or a suspected heart attack. Please consult your doctor, who will assess your specific test results and determine if an angiography is necessary and safe for you.
