| 内容記述 | Purpose: To estimate the clinical characteristics of obstructive hypertrophic cardiomyopathy (HOCM) and other diseases or conditions with left ventricular outflow tract obstruction (LVOTO). Methods: Forty cases (mean age 71 years, 31 women) with LVOTO (LVOT pressure gradient ≥ 30 mmHg) on resting transthoracic echocardiography were investigated and divided into two groups: HOCM group and other conditions (non HOCM group), and their clinical characteristics were compared. The mean follow-up period was 41 ± 8 months. Results: There were 17 patients (42.5%) in the HOCM group and 23 (57.5%) in the non HOCM group, with sigmoid septum being the most common (12 patients, 30%), followed by hypertensive heart (10%), takotsubo syndrome (7.5%). and small left ventricle with hyperkinetic wall motion (7.5%). Compared to the HOCM group, the non HOCM group was older (76 ± 10 vs. 67 ± 10 years, p = 0.006), had more frequent hypertension (HT) (78% vs. 47%, p = 0.041), and the mitral regurgitation severity at the first transthoracic echocardiography was significantly lower. Compared to the first LVOT velocity, the last LVOT velocity was significantly reduced in the HOCM group (4.6 ± 0.1 m/sec vs. 2.8 ± 1.8 m/sec, p = 0.001). However, there was no significant change in the non HOCM group (4.1 ± 1.0 m/sec vs. 3.3 ± 1.1 m/sec, p = 0.100). The frequency of cardiovascular events showed no significant difference between the 2 groups. Conclusions: This study showed different clinical background and change of LVOT velocity during follow-up periods in both groups. As the population ages, the patients with various LVOTO will increase further. It is important to investigate factors causing LVOTO and comprehensive management are required individually. |
