Changes in the QRS complex and ST segment in transmural and subendocardial myocardial infarctions. A clinicopathologic study.

abstract：BACKGROUND:Patients with heart failure (HF) frequently have comorbidities. Frequency, prognostic, and therapeutic implications of chronic obstructive pulmonary disease (COPD) in HF are largely unknown. We aimed to assess the prevalence and prognostic implications of COPD in a sample of stable patients with HF and to de...
