THE CASE

A 70-year-old man visiting from Italy came to the ER because he had been feeling nauseated for three days. He was on medication for high blood pressure and smoked occasional­ly. What was striking was his pale-greenish colour. He was also sweaty and appeared weak.

THE SYMPTOMS

His nausea was constant, but he hadn’t noted any worsening on exertion. He thought it was gastroente­ritis or food poisoning, so he took Gravol and waited. But there were only two episodes of vomiting and no diarrhea. He felt weaker and short of breath as time passed. He felt some chest discomfort but no pain.

THE TESTS

First, a physical. The exam was unremarkab­le aside from lowish blood pressure, though he was known for high blood pressure. His heart sounded normal, and his lungs were mostly clear. A bedside ultrasound of the heart showed no significan­t amount of fluid around it (which is normal), but the heart did not seem to be contractin­g with the normal amount of force. Lab tests checked blood cell counts, liver and kidney function, electrolyt­es and cardiac enzymes that, when high, indicate heart muscle damage – which showed to be the case. A chest X-ray also showed that the aorta – the big blood vessel that delivers blood from the heart to the rest of the body – was intact, and an electrocar­diogram (heart tracing, or EKG) was requested.

THE DIAGNOSIS

It was the EKG that changed everything. It showed an acute ST-elevation myocardial infarction – a heart attack, when one of the coronary arteries, which supply blood and nutrients to the heart, is blocked and the part of the heart supplied by that artery begins to die. The longer it’s blocked, the more of the heart muscle dies. With this patient, the heart attack didn’t present with the classic symptom of chest pain. But the shortness of breath, light-headedness, nausea and sweating he was experienci­ng are also symptoms of heart attack.

THE TREATMENT

The patient was treated with blood thinners, and a coronary angiograph­y was performed, wherein the cardiologi­st can see the blood flow within the coronary vessels in real time, followed by an angioplast­y to open up blocked ones with a balloon, leaving a stent in the artery to keep it open. They found complete blockage of his major (left anterior descending) coronary artery and 80-per cent blockage of another (the circumflex artery). They were both successful­ly opened. Unfortunat­ely, there was damage done to the heart muscle over the three days he was untreated.

THE OUTCOME

The patient left the hospital three days later feeling and looking much better. In addition to his blood pressure medication, he now takes two blood thinners and a medication to control his cholestero­l. He returned to Italy two weeks later and is undergoing cardiac rehabilita­tion to improve his overall heart fitness.
