*
It was not possible to identify the groups in which the differences occurred.
**
Statistically significant differences compared with HF patients with preserved LVEF.
***
Statistically significant differences compared with systolic HF patients.
****
Statistically significant differences compared with patients without HF. HF: heart failure. LVEF: left ventricular ejection fraction. SD: standard deviation. BMI: body mass index. SAH: systemic arterial hypertension. TIA: transient ischemic attack. AMI: acute myocardial infarction. TIMI: thrombolysis in myocardial infarction. NSTEMI: acute myocardial infarction without ST-segment elevation.
