Numerous etiologies in clinical practice can lead to chronic heart failure. Among these, infection is relatively common: following infection, certain inflammatory cytokines may act directly on cardiomyocytes, inhibiting myocardial contractility and thereby triggering chronic heart failure. Additionally, excessive dietary sodium intake or overly rapid or excessive intravenous fluid administration can cause prolonged expansion of intravascular volume, leading to increased cardiac preload and afterload—ultimately resulting in secondary chronic heart failure.
