Heart Disease Diagnosis

A complete blood count (CBC) is a blood test that measures various components of the blood, including red blood cells, white blood cells, and platelets. While a CBC can provide information about the health of the blood, it is not a specific test for detecting heart problems.

A blood test cannot directly detect blocked arteries, but certain blood tests can provide information on the risk factors associated with developing blockages in the arteries. For example, a high level of LDL cholesterol or triglycerides in the blood can increase the risk of developing plaque in the arteries, which can lead to blockages.

There is no one "best" test to check the heart as different tests serve different purposes. However, some commonly used tests to evaluate heart health include electrocardiogram (ECG or EKG), echocardiogram, stress test, cardiac catheterization, and coronary angiography. The choice of test(s) depends on the individual's symptoms, medical history, and the suspected heart condition.

Yes, an electrocardiogram (ECG) can detect heart failure. In fact, an ECG is one of the first tests that a doctor may order when evaluating a patient for heart failure. An ECG measures the electrical activity of the heart and can identify abnormal rhythms or patterns that may indicate heart failure. However, an ECG alone cannot definitively diagnose heart failure and other tests, such as an echocardiogram or blood tests, may be needed to confirm a diagnosis.
