BackgroundAbdominal obesity is an important cardiovascular risk factor. Therefore,
identifying the best method for measuring waist circumference (WC) is a
priority.ObjectiveTo evaluate the eight methods of measuring WC in patients with acute coronary
syndrome (ACS) as a predictor of cardiovascular complications during
hospitalization. MethodsProspective study of patients with ACS. The measurement of WC was performed by
eight known methods: midpoint between the last rib and the iliac crest (1), point
of minimum circumference (2); immediately above the iliac crest (3), umbilicus
(4), one inch above the umbilicus (5), one centimeter above the umbilicus (6),
smallest rib and (7) the point of greatest circumference around the waist (8).
Complications included: angina, arrhythmia, heart failure, cardiogenic shock,
hypotension, pericarditis and death. Logistic regression tests were used for
predictive factors. ResultsA total of 55 patients were evaluated. During the hospitalization period, which
corresponded on average to seven days, 37 (67%) patients had complications, with
the exception of death, which was not observed in any of the cases. Of these
complications, the only one that was associated with WC was angina, and with every
cm of WC increase, the risk for angina increased from 7.5 to 9.9%, depending on
the measurement site. It is noteworthy the fact that there was no difference
between the different methods of measuring WC as a predictor of angina. ConclusionThe eight methods of measuring WC are also predictors of recurrent angina after
acute coronary syndromes.
