Clinical localization of coronary obstruction based on the characteristics of cardiac pain

Chest Pain in Acute Myocardial Infarction and Its Association With the Culprit Artery and Fibrotic Segment Identified by Cardiac Magnetic Resonance

“…Our data did not corroborate these statements; irradiation to right upper limb occurred in RCA lesions in four of the patients (4.5%), LCX in zero (0%) and LAD in three of the individuals (2.7%), without statistical significance. The same result occurred in the irradiation to According to Macruz et al [3], in the analysis of obstruction in the LCX, in the presence of dominant RCA, the irradiation was to the left region, upper limbs and higher regions; the irradiation was bilateral when LCX was dominant. In our data, this association was also not statistically significant.…”

“…In 1973, Macruz el at [ 3 ] evaluated the importance of cardiac pain characteristics, such as location, quality, and irradiation, described by 151 patients with acute and chronic coronary insufficiency, to determine the location of coronary obstruction. In our study, we decided to reassess this information only in individuals with STEMI, as well as to evaluate the association between cardiac pain and the injured myocardial segments, with the anatomical refinement obtained through the CMR.…”

“…Although cardiac chest pain was frequent in our patients, it was not able to indicate with statistical significance an association between its location and the artery responsible for the STEMI. Macruz et al [3] did not identify an association between the arteries responsible for the event and the region where the pain was located. These authors reported that in the RCA occlusion, four patients described pain in the precordial region, one in the retrosternal region, one in the forearms and none in the epigastric.…”

“…“Angina pectoris is the most important clinical expression of coronary insufficiency or myocardial hypoxia” [ 3 ]. “Chest pain is the most common symptom of coronary artery disease and should not be described as typical but as cardiac, possibly cardiac and non-cardiac” [ 4 ].…”

“…In the past, it had believed that the localization and irradiation of the cardiac pain in coronary artery disease were associated with the culprit coronary artery [ 3 ]. Our aim was to evaluate whether these characteristics of the cardiac pain were associated with the artery responsible for the ST-segment elevation myocardial infarction (STEMI).…”
