of the patients were diagnosed with non-ST elevated myocardial infarction (NSTEMI), 36.8% with ST elevated myocardial infarction (STEMI), 3.41% with unstable angina, 0.56% with stable angina, and 0.11% were diagnosed with various types of arrhythmias. Approximately 48.5%

Background On the one hand, the primary coronary slow flow phenomenon (CSFP) can cause recurrence of chest pain, prompting medical examinations and further healthcare costs, while on the other hand, it can lead to myocardial infarction, ventricular arrhythmia and sudden cardiac death.

There are three mechanisms of arrhythmia: automatic, re-entry, and triggered. The most common triggered arrhythmia is Torsades de Pointes. It is a benign arrhythmia which requires no specific treatment. Possible mechanisms of ventricular arrhythmias elicited by ischemia followed by reperfusion. Do not treat AIVR.

So there is probability of myocardial injury here (and because it is in the correct clinical setting, then myocardial infarction.) Thus, the patient does not (yet) get a formal diagnosis of MI and must be called unstable angina unless further troponins return above the 99th percentile. Repeat ECG is shown below.

Therefore, this does not meet the definition of myocardial infarction ( 4th Universal Definition of MI ), which requires at least one troponin above the 99% reference range. This was clearly severe subepicardial ischemia causing ST Elevation, but it was not of a long enough duration to result in measurable infarct.

Angina is another common symptom due the hypertrophy which causes a coronary supply demand mismatch Symptoms of HCM include syncope/near syncope, which could be precipitated by exertion, hypovolemia, rapid standing, Valsalva manoeuvre, diuretics, vasodilators or arrhythmia. Palpitations can be felt if there are arrhythmias.

Measurement of QT interval is very important, as QT prolongation can predispose to serious, life threatening ventricular arrhythmias. QT prolongation leads to torsades des pointes, which is a very serious arrhythmia. That is usually with angina and ventricular strain patterns. One easy value which I remember is 0.34
