心血管疾病的诊断 & 测试

心脏病检测的重要性

Approximately 80 million Americans have some form of heart disease. Saint Francis Medical Center’s 心医院 uses the latest tests and procedures to diagnose heart-related disorders before they become fatal. Stress tests, blood pressure monitoring, and angiography are effective diagnostic tools.

血管造影术

An angiography is an X-ray test used to detect diseases of the blood vessels, such as the weakening of the vessel walls and the narrowing or blocking of vessels. The X-ray is taken after the vessels are injected with a substance that enables them to be captured on film. 

血压监测

Because high blood pressure is one of the three main factors associated with heart attacks, it is important to check your blood pressure regularly. We monitor the blood pressure of our 心医院 patients around the clock.

CT

The computerized tomography (CT) scanner helps identify aortic disease, 心脏肿块和心包疾病. 

64 - CT切片

The 64 - CT切片 is a powerful computer-driven scanner that can capture vividly detailed 3-D images in 5-10 seconds (compared to 30-40 seconds for previous CT scanners) and provide unprecedented clarity with full-color, high-resolution imaging for early detection of various diseases and pathologies to more accurately diagnose and treat patients.

心脏钙评分

Cardiac calcium scoring uses high-speed CT technology to take rapid pictures of the heart and the arteries around it to detect calcium or plaque buildup. Plaque causes hardening of the arteries and can lead to heart attack if left untreated. A scan is assigned a score from 0 (no calcification) to 400 (significant calcium buildup).

心电图

An electrocardiogram (心电图) measures the heart’s electrical activity to help diagnose abnormal heart conditions. The  physician monitors the 心电图 readings to check for irregularities in the heart rhythm.

分流储备

This measurement process occurs during the heart catheterization to aid in detecting a blockage significant enough to need intervention.

霍尔特监控

在心脏动态心电图检查中, a patient wears a monitor (usually for 24 hours) that records electrical activity of the heart. Saint Francis also offers 30-day Holter monitoring for appropriate cases. While being monitored, the patient also records a diary of his/her activity. Heart care specialists then analyze the data to diagnose any irregularities.

血管内超声

Intravascular ultrasound enables doctors to view coronary anatomy during diagnostic and interventional catheterization to identify a blockage that is significant enough to require intervention.

核磁共振成像

Magnetic resonance imaging (核磁共振成像) uses powerful magnets to look inside the body. Computer-generated pictures can show the heart muscle, 识别心脏病发作造成的损害, diagnose certain congenital cardiovascular defects and evaluate disease of larger blood vessels.

P.E.T. 扫描

正电子发射断层扫描(P.E.T.) scanner is an imaging test that shows how organs function rather than just how they look. Functional abnormalities usually occur long before structural damages are evident, 使早期发现疾病成为可能.

压力测试

  • 运动压力测试: Physical exercise is performed on a treadmill while your heart is monitored. If you are having nuclear images done with this exam, a radioactive medication is administered while you are exercising.
  • 化学压力测试: If you are unable to perform physical exercise, then your physician may order a chemical stress test. 包括腺苷在内的各种化学物质, 多巴酚丁胺, Persantine or Lexiscan may be used to exercise the heart in place of physical exercise. If you are having nuclear images done with this exam, 同时还使用放射性药物. This type of stress test is always done with either an echocardiogram or nuclear imaging.
  • 超声心动图压力: 在超声心动图中, ultrasound images of your heart are taken during various stages of cardiac stress. 取决于你的身体状况, you may have an exercise stress test or chemical stress test associated with your stress echocardiogram.
  • 核压力试验: You will have two injections of a radioactive medication to allow for images of the blood flow to your heart. One injection and image will before the stress test and one injection will be during the stress test with images after. 取决于你的身体状况, you will have either an exercise or chemical stress test as listed above associated with the imaging.

技术超声心动图

A transesophageal echocardiogram is a special type of imaging procedure that uses a tube with a transducer on the end of it. The tube is passed down your throat into the esophagus to get very clear images of your heart and its structure.
