Our hearts beat about 100,000 times each day (maybe more if you enjoy horror movies). Despite being extremely complex, our hearts are exceptionally reliable. So, it’s safe to say, you probably don’t think about your heart very often.
That’s OK most of the time but looking after our heart’s health should be a priority for everyone. According to the Centers for Disease Control and Prevention (CDC),heart disease is the leading cause of deathfor both men and women in the U.S. And8.5% of those deaths根据美国心力衰竭社会（HFSA）直接与心力衰竭有关。
心力衰竭通常分为两类：收缩和舒张。随着收缩心力衰竭，你的心脏并不收缩during心跳。相比之下，舒张心脏衰竭，是你的心脏无法正常放松的时候betweenbeats.
The differences don’t stop there — and the differences are important.
Namit Rohant, MD, a cardiology specialist at横幅 - 大学医学北在艾茨图森，与我们谈论心力衰竭的症状以及两种类型与各自治疗之间的关键差异。
心力衰竭的症状
Both conditions involve the heart’s left ventricle, and the symptoms for both may feel very similar if you experience them. Both diastolic and systolic heart failure have the following symptoms:
- 日常活动期间呼吸急促
- Difficulty breathing when lying down
- Weight gain with swelling in the feet, legs, ankles or stomach
- Generally feeling tired or weak
部t how you treat systolic and diastolic heart failure can differ quite a bit.
Systolic heart failure
Systolic heart failure, or when your heart struggles to contract during heartbeats, is considered thefinal manifestationor outcome of several heart conditions, and is also called heart failure with reduced ejection fraction (HFrEF).
射血分数(EF)是一口,肯定的。部t it’s an important measure. In simple terms, it measures the percentage of blood your heart pushes out with each pump. The more the heart pumps out, the healthier it is. An EF between 50 and 70 is normal. If it’s below 40, then that signals systolic heart failure.
“Over the years, systolic heart failure has had a lot of promise with medical therapy,” Dr. Rohant recalled. He outlined four types of medication that are typically used to treat it:
- Beta阻滞剂（BB）
- Angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARB), or angiotensin receptor neprilysin inhibitors (ARNI)
- Mineralocorticoid receptor antagonists
- 钠葡萄糖运输蛋白2（SGLT2）抑制剂
Dr. Rohant said these medications have been studied in a variety of different trials with diverse patients — and when it comes to systolic heart failure, they’ve been shown to reduce mortality and hospitalizations.
通常，收缩性心力衰竭比舒张性心力衰竭更好地理解。治疗的进步意味着更加激烈的干预（植入物，手术，移植）在后面的治疗过程中掺入了比以前的方式。
舒张心衰竭
当你的左心室僵硬时，不能在节拍之间放松，那是舒张性心力衰竭。它也称为残留的喷射分数（HFPEF）的心力衰竭。有这种情况的人可以具有正常的ef-意味着它抽出的可用血液的百分比是正常的。但被泵送的血液量较少，因为在每次节拍之前，节拍之间没有放松的心脏并不完全填充血液。
Rohant博士解释说，许多其他条件有时会模仿心力衰竭。因此，为了确定患者的心力衰竭是舒张性的，医生会看看患者体重，高血压病史，不规则心律的历史，年龄，心脏实验室工作和一些超声心动图测量。如果这些其他因素表明患者的心脏僵硬，那么问题实际上可能是舒张性的。
Unfortunately, the medicines that have proven successful for systolic heart failure haven’t been as successful with diastolic heart failure. So, this condition still has a lot of unknowns. But in general, the main approaches for treating diastolic heart failure with medication include:
- 用于放松或拓宽血管的药物：ARB，BBS，钙通道阻滞剂或长效硝酸盐，以及诸如硝基甘油等血管扩张剂
- Medications to reduce fluid build-up: i.e. diuretics
- Medications to control other conditions, like high blood pressure
Getting better (and staying better)
According to Dr. Rohant, patients often think that once they start feeling better, it means they can stop taking meds and practicing healthier lifestyle habits. This just isn’t the case, for both systolic and diastolic heart failure.
“这些药物和生活方式的修改是让他们再次开始感觉，”他解释说，添加了心脏药物可以控制和治疗心力衰竭，但不能直接治愈它。
For people with heart conditions, there is plenty of good news. And80% of cardiovascular diseaseis preventable, according to the American Heart Association. Early detection and consistent treatment are key. So, if your doctor has prescribed you a certain heart medication, and it’s working, then keep taking it.
