Diagnosis of Left Ventricular Failure

In this article we will discuss the Diagnosis of Left Ventricular Failure

In this article, we will discuss the Diagnosis of Left Ventricular Failure. So, let’s get started.

Investigations

  • Full blood count, blood urea, creatinine, electrolytes, etc.
  • Arterial blood gas analysis may show low PaO2 with normal or low PaCO3 and low blood pH (metabolic acidosis)
  • The ECG may show LVH, arrhythmias, evidence of ischemia or myocardial infarction, LBBB or ventricular strain pattern depending on the cause of LVF
  • Chest X-ray will show pulmonary edema (haziness extending from the hilum to periphery) and cardiomegaly. Karley’s B lines may be seen due to alveolar edema. Hydrothorax or left-sided pleural effusion may be evident
  • Echocardiogram is most useful investigation and is mandatory in all patients with acute cardiogenic pulmonary edema. It gives valuable information regarding:

(a) Unsuspected yet correctable valvular lesion(s)

(b) Unsuspected cardiac aneurysm

(c) Hypertrophic or dilated cardiomyopathy

(d) Systolic or diastolic LV dysfunction

  • Pulmonary capillary wedge pressure is elevated, may be above 25 mmHg. The pulmonary capillary wedge pressure indirectly reflects left atrial pressure.
