Patient characteristics
Patient characteristics are shown in Table 1 (N=105). Mean age was
79.9±6.4 years, and 43% were male. In total, 9% of patients had a
history of paroxysmal atrial fibrillation, but had sinus rhythm at the
time of echocardiography. HR and BP were controlled (HR 63.2±10.9
beats/min, systolic BP 125.8±17.3 mmHg, and diastolic BP 65.4±11.1
mmHg). The mean serum BNP level was 65.8±83.2 pg/ml.
Echocardiographic parameters in the present study are shown in Table 2.
Patients mostly had preserved LVEF (67.3±5.6%) and diastolic
dysfunction. The average E wave was 59.3 cm/s, A wave 84.6 cm/s, and E/A
ratio 0.72. Most patients exhibited LA dilatation (LAVI 35.6±32.4
ml/m2).
