[Clinical and hemodynamic characteristics of ischemic heart disease in patients with deficient body mass].

AIM
To elucidate clinical and hemodynamic characteristics of patients with ischemic heart disease and low body mass.


MATERIAL
Patients with stable angina (n=162) divided into 3 groups according to body mass index (below 25, 25-27 kg/m2 and above 27 kg/m2).


RESULTS
Patients with low body mass index compared with those with intermediate values had worse clinical (arrhythmias, derangements of conduction, recurrent myocardial infarctions, cases with heart failure), hemodynamic (lower stroke volume and cardiac index, higher total peripheral resistance), and cardiometric (lower ejection fraction, larger diastolic volumes, greater relative myocardial mass) characteristics.


CONCLUSION
These findings constitute a pathophysiological substrate for increased risk of death in patients with ischemic heart disease and deficient body mass.
