Original Article Gil et al. LV function in HCM by Strain technique Arq Bras Cardiol. 2019; 113(4):677-684 Figure 1 – Flowchart of patient selection. MR: magnetic resonance; HCM: hypertrophic cardiomyopathy; SAH: systemic arterial hypertension. Potentially eligibles patients n = 55 Echocardiogram Excluded Patients (n = 8) – Atrial fibrillation (n = 6) – Known coronary disease (n = 2) Eligibles patients n = 47 Magnetic resonance Selecteds patients n = 45 HCM n = 31 HCM + SAH n = 14 Excluded Patients (n = 2) – Diagnosis not confirmed by MR Figure 2 – Phenotypic classification originally described by Maron. Type I: hypertrophy involving the basal septum; Type II: hypertrophy involving the entire septum; Type III: hypertrophy involving the septum and at least part of the left ventricular free wall (posterior, anterior or lateral); Type IV: other isolated locations (posterior, apical or lateral). Maron BJ. et al. 15 Mean blood pressure was higher in the hypertensive group. In this group, nine patients (64%) had increased blood pressure before the test, with 144x92 mmHg maximum. In the group without hypertension, six patients (19%) had a slight blood pressure increase with 135x84 mmHg maximum. Regarding the medications used, more medications were used by the group of hypertensive patients, especially angiotensin receptor blockers, calcium antagonists and diuretics. No patient was taking cardiotoxic drugs or any drugs interfering with ventricular function. 679
