Figure 3. Illustrative example of the diagnostic score application in a patient with suspected HFpEF. A 64-year-old female patient had a history of metabolic syndrome (obesity grade III – Body Mass Index: 35.6, systemic arterial hypertension and diabetes mellitus) and complaints of dyspnea on minimal effort (FC III NYHA). The ECG (above) showed signs of left ventricular hypertrophy according to the Sokolow-Lyon criteria. The TTE displays an interventricular septum and posterior wall thickness of 12 mm and LVMI: 105 g/m2 (1 point). The left atrial volume index estimated at the apical 4C (top left) and apical 2C (top right) views was 48 mL/m2 (2 points). Tissue Doppler shows e’ wave septal velocity = 4 cm/s (bottom left) and lateral e´ wave velocity = 3 cm/s (bottom right) (2 points). Thus, by applying the score for the diagnosis of HFpEF, the patient attained 5 points and, therefore, the HFpEF diagnosis was confirmed.
