a disorder in which the heart muscle is so strong that it does not relax enough to fill with the heart with blood and so has reduced pumping ability

hypertrophic cardiomyopathy is not related to ischemic heart disease but 50% of cases are familial and may be related to genetic mutations in genes encoding for cardiac contractile elements.

肥厚性心肌病与缺血性心脏病无关，但是50%的病例具有家族性并且与基因突变有关。突变基因一般为心脏收缩过程先关基因。
