Abstract
Introduction: A presentation consistent with an acute myocardial infarction without
obstructive lesions of greater than 50% and no other plausible explanation for the
clinical presentation at the time of angiography characterize myocardial infarction in
the absence of obstructive coronary artery disease (MINOCA). heart attack. MINOCA
is linked to a 5% 1-year death rate and accounts for 5% to 15% of AMI patients. In
older patients, Latin America has few characterizations of it. Methods: Medical data
from January 2021 to December 2023 in a South American hospital were reviewed as
part of a retrospective study. Included were patients who had coronary angiography
and were diagnosed with acute myocardial infarction based on the fourth universal
criteria. Results: Patients who satisfied the inclusion and exclusion criteria and were
over 65 years old up to 90 years old were included. There were a hundred patients in
all, including thirty-two women and sixty-eight men. 13 patients—8 women and 5
men—had MINOCA. The three most common comorbidities were diabetes (48%),
dyslipidemia (57%), and hypertension (69%). Every patient at MINOCA had diabetes.
Discussion: Where the MINOCA is up to 15%, a frequency comparable to research
from other latitudes was discovered. All of the cases with ST elevation myocardial
infarction had 8% fatality rates. There was no death among the MINOCA patients. We
highlight the necessity of doing bigger cohort studies in order to improve
characterisation, based on the results obtained here.
