That increases the resistance, and therefore decreases blood flow to the heart muscle.

这增加了阻力，因此减少了流向心肌的血流。

Our tests show that there has been major damage to the heart muscle.

检查结果表明他的心肌受到了很大的损伤。

There were also no cases of myocarditis or pericarditis — inflammation of the heart muscle or its lining.

试验中也没有心肌炎或心包炎的案例，这两种疾病分别是心脏肌肉或心脏外膜发炎。

Yet chemotherapy can weaken the heart muscle and some newer targeted medicines increase the risk of heart failure.

然而化疗会削弱心肌，一些新的靶向药物会增加心力衰竭的风险。

This pattern acted as a map on which cells from the heart muscle of a rat were grown.

这种特定蛋白质就好像是一张地图，在其表面上附着着生长好的老鼠心肌细胞。

A heart beats because every second electrical impulses spread through the heart muscle, triggering and coordinating a movement.

心脏跳动是因为每秒钟都有电脉冲通过心肌传播，触发并协调运动。

Now several mechanisms can lead to stiffer heart muscles and restrictive cardiomyopathies.

目前有几种机制可以导致心肌变僵硬以及限制型心肌病。

Restrictive cardiomyopathy is where the heart muscle is restricted, meaning it becomes stiffer and less compliant.

限制型心肌病，指心脏的肌肉被限制住了，意味着它变得僵硬，顺应性也变差。

They commonly use an electrocardiogram to measure the heart's electrical activity and a blood test to assess heart muscle damage.

他们通常使用心电图来测量心脏的电气活动并且做血液检查 来评估心肌的损伤。

The gene changed heart muscle cells -- called cardiomyocytes -- into natural pacemaker cells.

该基因将心肌细胞（称为心肌细胞）转变为天然起搏细胞。
