The rationale for our study was to investigate the pathophysiology of microvascular injury in
patients with acute ST-segment–elevation myocardial infarction in relation to a history of …

Background: Recent studies have shown a worse in-hospital outcome in hypertensive than
in normotensive patients with acute myocardial infarction (AMI), which has been attributed to …

Background Antecedent hypertension is associated with poor outcome in patients with ST-
elevation myocardial infarction (STEMI). Whether differences in myocardial salvage, infarct …

Acute kidney injury (AKI) is a frequent complication in patients with ST-elevation myocardial
infarction (STEMI) treated by primary percutaneous coronary intervention. However, the …

Background: The invasive microvascular function indices, coronary flow reserve (CFR) and
the index of microcirculatory resistance (IMR), exhibit a dynamic pattern after ST-segment …

Objectives Early detection of microvascular dysfunction after acute myocardial infarction
(AMI) could identify patients at high risk of adverse clinical outcome, who may benefit from …

Background: The resistive reserve ratio (RRR) expresses the ratio between basal and
hyperemic microvascular resistance. RRR measures the vasodilatory capacity of the …

Background—A total of 40% to 50% of patients with ST-segment–elevation myocardial
infarction develop microvascular injury (MVI) despite angiographically successful primary …

Background Microvascular injury (MVI) after primary percutaneous coronary intervention for
ST‐elevation myocardial infarction (STEMI) is a major determinant of adverse clinical …

Previous studies analyzing the impact of hypertension (HTN) on myocardial infarction (MI)
outcome reached conflicting results and scarce data are available in patients treated with …
