is st segment depression dangerous?

Conclusions: In unstable coronary artery disease, ST-segment depression is associated with a 100% increase in the occurrence of three-vessel/left main disease and to an increased risk of subsequent cardiac events. In these patients an early invasive strategy substantially decreases death/myocardial infarction.

Angina is chest pain caused by reduced blood flow to the heart muscles. It's not usually life threatening, but it's a warning sign that you could be at risk of a heart attack or stroke. With treatment and healthy lifestyle changes, it's possible to control angina and reduce the risk of these more serious problems.

Unstable angina belongs to the spectrum of clinical presentations referred to collectively as acute coronary syndromes (ACSs), which also includes ST-segment elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI).

Inappropriate sinus tachycardia (IST) is not a life threatening condition although for some people it can have major effects on their day to day life. There is no proof that having IST increases the risk of other heart problems.

Tell your doctor immediately if any of these unlikely but serious side effects occur: fast/irregular/pounding heartbeat, mental/mood changes (e.g., agitation, uncontrolled anger, hallucinations, nervousness), uncontrolled muscle movements, change in sexual ability/interest.

When you have SVT, the electrical system in your heart isn't working right. You might experience a sudden rapid heartbeat, which can lead to shortness of breath, chest pain and, in rare cases, loss of consciousness. SVT often ends suddenly. It stops either on its own or when you take an action to slow your heart rate.

IST is not a life threatening condition but it can be very debilitating. Where sinus tachycardia is identified it is important to rule out other treatable conditions before making the diagnosis of IST – it may be that there is a curable cause.

Reciprocal change is a very important ECG finding, not only supporting the diagnosis of STEMI but also indicating a high-risk patient. Reciprocal change is defined as ST-segment depression occurring on an ECG which also has ST-segment elevation in at least 2 leads in a single anatomic segment.

If you have been diagnosed with coronary artery disease, AVNRT may cause angina (chest pain) or heart attack. It can also worsen heart failure if your left ventricle (the lower heart chamber that pumps blood to the body) functions poorly.

If you have an EF of less than 35%, you have a greater risk of life-threatening irregular heartbeats that can cause sudden cardiac arrest/death. If your EF is below 35%, your doctor may talk to you about treatment with an implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy (CRT).

The more damage there is, the harder it is for your heart to pump. This leads to pain, fatigue (feeling very tired), shortness of breath and other symptoms that affect your quality of life.

Important warnings. Heart attack: This drug can cause serious heart problems such as heart attack, angina (chest pain), or cardiac arrest. If you're at risk for heart disease, your doctor may have you take your first dose in their office so they can monitor you.

Depression prevalence has also been reported as high in SCD. Clinical depression may lead to decreased compliance with prescribed medical treatments, and thus deteriorating function and health status. Furthermore, depressed patients report more frequent painful episodes.

ST-Elevation Myocardial Infarction (STEMI) is a very serious type of heart attack during which one of the heart's major arteries (one of the arteries that supplies oxygen and nutrient-rich blood to the heart muscle) is blocked. ST-segment elevation is an abnormality detected on the 12-lead ECG.

Inferolateral ST depression, T wave inversion, and QT prolongation have been frequently described in reports of largely symptomatic mitral valve prolapse (MVP) patients, but not in a recent population-based survey of mainly asymptomatic subjects with MVP.

Hypotension can be dangerous because it's a frequent cause of falls. Isolated diastolic hypotension can be especially dangerous because it can decrease blood flow to your heart. You may be at higher risk if you have coronary artery disease. Over time, isolated diastolic hypotension can cause heart failure.
