  Figure 5. Heatmap of correlation between covariates for the multiple linear regression model of KCCQ-12 score in patients with hypertrophic cardiomyopathy. A digit in each square indicates the Pearson’s correlation coefficient of each comparison. T90 (%) indicates the percentage of cumulative time with oxygen saturation below 90% in total sleep time. AF, atrial fibrillation; eGFR, estimated glomerular filtration rate; KCCQ, Kansas City Cardiomyopathy Questionnaire; LV, left ventricle; LVOT, left ventricular outflow tract; NT-proBNP, N-terminal pro-B-type natriuretic peptide; ODI, oxygen desaturation index; PG, pressure gradient; PSQI, Pittsburgh Sleep Quality Index; VF, ventricular fibrillation; VT, ventricular tachycardia.

T90 (%) indicates the percentage of cumulative time with oxygen saturation below 90% in total sleep time. AF, atrial fibrillation; eGFR, estimated glomerular filtration rate; LV, left ventricle; LVOT, left ventricular outflow tract; NT-proBNP, N-terminal pro-B-type natriuretic peptide; PG, pressure gradient; PSQI, Pittsburgh Sleep Quality Index; VF, ventricular fibrillation; VT, ventricular tachycardia.
