Study population: All adults aged 18 years and above admitted with a diagnosis of acute ST elevation myocardial infarction will be asked about the potential presence of a triggering event prior to the heart attack as well the exact timing (hour of the day and the day of the week) when the pain of the heart attack started.

Furthermore these patients will be followed up for 3 years to study the occurrence of future cardiovascular event at 3 years. These events include all-cause death, myocardial infarction, stroke, heart failure and repeat coronary revascularization (percutaneous of surgical).

Brief summary: A previous study (MINTOR 1) found that 43% of ST elevation myocardial infarction (STEMI) patients in Jordan had a triggering events. Fifteen years later, with changing demographics and in the post covid-19 time, we believe that triggered acute myocardial infarction might have changed in incidence and nature of the triggering events.

Detailed description: The onset of acute ST elevation myocardial infarction (STEMI) is a complex interplay of internal circadian factors and external physical and emotional triggers. These interactions may lead to rupture of an often nonocclusive vulnerable atherosclerotic coronary plaque with subsequent formation of an occlusive thrombus. The onset of MI has a distinct pattern, with peak incidence within the first few hours after awakening, on certain days of the week, and in the winter months. Physical and emotional stresses are important triggers of acute cardiovascular events including MI. Triggering events, internal changes, and external factors vary among different geographical, environmental, and ethnic regions. Life-style changes, pharmacotherapy, and psychologic interventions may potentially modify the response to, and protect against the effects of triggering events.

MINTOR 1 showed that 43% of 900+ Jordanians with STEMI were exposed to a physical or emotional triggers before the onset of the heart attack. It was also found that Friday was the day of the week that witnessed more MIs that other days of the week and that 55% of MIs occurred in the early morning hours.

It is largely unknown if the frequency and types of triggers, onset time of MI, day with peak of MI incidence have changed over time in Jordan with changing population demographics, especially in the post Covid-19 times. These patients will be followed up for 3 years for occurring of incident vascular events.
