Original Article Gil et al. LV function in HCM by Strain technique Arq Bras Cardiol. 2019; 113(4):677-684 Figure 4 – Graphs showing the main results of patients with hypertrophic cardiomyopathy (HCM) with and without associated systemic arterial hypertension (SAH). The analyzed STRAIN is the global longitudinal strain. LVH refers to the types of left ventricular hypertrophy (I, II, III, and IV) and diastolic function refers to types I, II, and III. –6 –8 –10 –6 –4 4.0 3.0 2.0 1.0 4.0 3.0 2.0 1.0 –8 –10 –12 –14 –12 –14 –16 –18 –20 –6 –8 –10 –12 –14 –16 –18 –20 –6 –8 –10 –12 –14 –16 –18 –20 –6 –8 –10 –12 –14 –6 –4 –8 –10 –12 –14 –16 –18 –20 HCM HCM HCM HCM HCM and SAH HCM and SAH HCM and SAH HCM and SAH DIASTOLIC FUNCTION DIASTOLIC FUNCTION AGE AGE STRAIN STRAIN STRAIN STRAIN STRAIN STRAIN SAH SAH 0 1.0 2.0 0 1.0 2.0 3.0 20 30 40 40 45 35 50 50 55 60 60 65 70 Table 2 – Demographic data Variables Normotensive patients (n = 31) Hypertensive patients (n = 14) p Measures LVDD (mm) 4.56 ± 0.66 4.76 ± 0.60 0.3485 LVSD (cm) 2.42 ± 0.49 3.45 ± 0.46 0.0008 S/PW 2.03 ± 0.65 1.63 ± 0.44 0.0425 LA volume (ml/m 2 ) 37.76 ± 17.14 38.97 ± 16.79 0.8245 RV (cm) 1.70 ± 0.43 1.71 ± 0.31 0.9757 EF% (Teichholz) 80.18 ± 5.76 74.01 ± 9.90 0.0116 E (cm/s) 78.23 ± 16.30 76.13 ± 26.83 0.7465 A (cm/s) 50.92 ± 16.92 80.70 ± 22.71 < 0.001 E/A 1.57 ± 0.56 0.96 ± 0.25 0.0003 EDT (ms) 241.90 ± 79.15 261.00 ± 66.23 0.4363 IVRT (ms) 119.94 ± 24.90 141.50 ± 35.08 0.0228 septal e’ (cm/s) 5.75 ± 1.30 4.43 ± 0.95 0.0015 lateral e’ (cm/s) 8.37 ± 2.79 7.21 ± 3.47 0.2386 Septal E/e’ 13.98 ± 4.26 17.45 ± 6.21 0.0327 Lateral E/e’ 10.18 ± 3.81  12.90 ± 6.81 0.0926 Mean E/e’ 12.40 ± 3.73 15.71 ± 6.21 0.0696 Diastolic dysfunction classification Undetermined 41.9% 7.1% 0.0242 Grade 1 12.9% 50.0% Grade 2 41.9% 42.9% Grade 3 3.2% 0.0% Values expressed as mean±standard deviation or proportion, as indicated.
