Recognizing Coronary Artery Disease Before It Becomes a Heart Attack

RFCL is an old scoring system we do not use anymore; it produces more false negatives than anything useful. Score this patient with a EuroSCORE now, and a SYNTAX score once an angiogram is available.

Before 45, women have high estrogen and regular cycles, giving them roughly one-eighth the coronary risk of a man. After menopause, that risk is still about half of a man's, but it rises four-fold from her own prior baseline. The presentation also changes: expect a longer course, days rather than hours, with softer symptoms, a flu-like feeling or mild chest tightness, that get mistaken for a common cold. The best test in this group is a CT coronary angiogram, because women tend to have a lower coronary calcium load, which gives CT angiography a strong positive predictive value for them specifically. Diabetics have a parallel but distinct problem: autonomic nerve involvement blunts the pain signal, so they report less chest pain for the same severity of disease while still showing the nausea, fatigue and cold extremities of an infarction. Physicians need to actively look for the disease in diabetics rather than wait for classic pain.

The same as anyone else. He gets a coronary angiogram under a universal precautions pathway, and if he has coronary artery disease, it is stentable or operable exactly as it would be otherwise. Any JCI-accredited hospital, ours included, has a protocol to isolate and properly treat these patients. People living with HIV are not discriminated against in access to stenting or bypass surgery.

The two are differentiated by troponin: a pectoralis muscle spasm will always return a negative troponin test. There is not really a single first-choice management for a direct link between the two, because they do not co-occur as one diagnosis; one patient might have non-cardiac chest pain from a muscle spasm and separately have coronary disease. Treat each on its own terms: non-steroidal anti-inflammatory drugs for the muscle spasm, and the angiography pathway, deciding between angioplasty and bypass, if there is genuine coronary disease.

Optimal nutrition means a high-protein, high-fiber, low-fat, low-carbohydrate diet. Combined with the rest of the prevention checklist, no smoking, more than two hours of exercise a week, regular stress management, and routine blood work from age 40 onward, this kind of consistent lifestyle management can prevent coronary artery disease from progressing to the point of needing an intervention in roughly 80 percent of patients.

Chest pain, breathlessness, unusual fatigue, pain in the legs, a generalized feeling of being unwell, and weakness. Any one of these on its own is reason enough to see a general practitioner.

The practical marker is functional decline relative to a recent baseline: no longer being able to do independently, comfortably, the tasks that were manageable a month or two earlier.

If it persists for more than half an hour after a standard over-the-counter antacid or indigestion medication, that is the signal to see a general practitioner immediately rather than take a second dose.

They tend to appear in the disease course well before a myocardial infarction. That earlier stage is where lifestyle changes, medical therapy and risk stratification can still change the outcome without a surgical or percutaneous intervention.
