Even though systolic failure is most common in left-sided heart failure, diastolic heart failure or filling dysfunction can also happen.

尽管收缩性心衰是左侧心力衰竭最主要病因，舒张性心力衰竭或充盈障碍也有可能发生。

So restrictive cardiomyopathy causes heart failure, and since filling happens during diastole, we say this is a type of diastolic heart failure.

因此限制型心肌病会导致心力衰竭，且由于血液进入心室发生在舒张期，所以我们说它是一种舒张期心力衰竭。

Now in addition to systolic heart failure, you've also got diastolic heart failure, which is where the heart's squeezing hard enough but not filling quite enough.

除收缩性心衰外，还有舒张性心力衰竭，指的是心脏收缩功能正常，但是在舒张期充盈受损。

In this case the heart muscle gets stiffer and less compliant, and therefore the left ventricle can't easily stretch out and fill with as much blood, which leads to diastolic heart failure.

在这种情况下，心脏肌肉变得僵硬，同时顺应性下降，因此左心室不能轻易地伸展，无法有效充盈，从而导致舒张性心衰。

This can happen in two ways, either the heart's ventricles can't pump blood hard enough during systole, called systolic heart failure, or not enough blood fills the ventricles during diastole, called diastolic heart failure.

这可能以两种方式发生：一种是心室在心脏收缩期不能足够有力地泵出血液，即收缩性心力衰竭；另一种是在心脏舒张期心室充盈不足，即舒张性心力衰竭。

This means that as the heart muscle wall enlarges, it crowds into the ventricular chamber space, resulting in less room for blood, meaning that in addition to contributing to systolic dysfunction, hypertension also can cause diastolic heart failure.

随着心壁扩大，它也挤入了心室空间，导致血液空间缩小，也就是说，除了致使收缩期功能不全之外，高血压也能导致舒张性心力衰竭。
