The research used information from KRAMI-RCC, a registry of myocardial infarction sufferers within the Republic of Korea.2 Trained nurses requested survivors in the event that they recognised the next myocardial infarction signs: 1) chest ache, 2) shortness of breath, 3) chilly sweats, 4) radiating ache to the jaw, shoulder or arm 5) dizziness/vertigo/lightheadedness/lack of consciousness and 6) abdomen ache. Patients have been categorised as “recognised symptoms” if they might establish at the very least one symptom; in any other case they have been categorised as “did not recognise symptoms”. The researchers in contrast affected person traits, time to life-saving therapy and survival between the 2 teams after adjusting for age 70 years and above, intercourse, schooling, dwelling with a partner, earlier registration in KRAMI RCC, most cancers, dyslipidaemia, cardiogenic shock and presence of acute decompensated coronary heart failure.
The research included 11,894 myocardial infarction sufferers, of whom 10,623 (90.4%) had a first-time occasion and 1,136 (9.6%) had a repeat occasion. Of the 1,136 sufferers with a repeat occasion, 118 have been excluded because of lacking information, failure to reply the survey about signs, or presentation with cardiac arrest, leaving 1,018 sufferers for the analyses. Overall, simply over half (52.3%) of sufferers recognised the signs of myocardial infarction. The majority of sufferers (92.9%) might establish chest ache as a symptom of myocardial infarction, whereas roughly one-third recognised shortness of breath (32.1%) and chilly sweats (31.4%). Just over one in 4 recognised radiating ache (27.4%), whereas solely 7.5% recognized /vertigo/lightheadedness/lack of consciousness and 1.3% recognised abdomen ache.
Regarding affected person traits, males have been extra prone to recognise signs than ladies (79.3% of males vs. 69.0% of ladies recognized signs). Other traits related to symptom recognition have been youthful age, larger schooling degree and dwelling with a partner.
The researchers additionally in contrast time to therapy and outcomes between the 2 teams. Some 57.4% of sufferers who appropriately recognized the signs of myocardial infarction acquired therapy to open the arteries and restore blood stream inside two hours, in comparison with simply 47.2% of those that didn’t recognise the signs. Patients who recognised signs had a decrease in-hospital mortality price (1.5%) in contrast with those that couldn’t establish the signs of a coronary heart assault (6.7%). The group who couldn’t recognise signs extra usually had cardiogenic shock and coronary heart failure.
Among sufferers with recurrent myocardial infarction, the symptom recognition price was 57.5% for these beforehand enrolled in KRAMI-RCC and 43.2% for these not beforehand enrolled. Just 14.4% of sufferers with a first-time myocardial infarction might establish the signs.
Dr. Kim mentioned: “The findings indicate that education is needed for the general public and heart attack survivors on the symptoms that should trigger calling an ambulance. In our study, patients who knew the symptoms of a heart attack were more likely to receive treatment quickly and subsequently survive. Women, older patients, those with a low level of education, and people living alone may particularly benefit from learning the symptoms to look out for.”
