A coronary stent is a tube-shaped device placed in the coronary arteries that supply blood to the heart, to keep the arteries open in patients suffering from coronary heart disease. The vast majority of stents used in modern interventional cardiology are drug-eluting stents (DES).
Symptoms may also suggest or signal restenosis, but this should be confirmed by imaging. For instance, a coronary stent patient who develops restenosis may experience recurrent chest pain or have a minor or major heart attack (myocardial infarction), though they may not report it. This is why it is important that a patient comply with follow-up ...
Yet heart problems often produce no symptoms until very advanced, and many symptoms, such as palpitations and sensations of extra or missing heart beats correlate poorly with relative heart health vs disease. Hence, a history alone is rarely sufficient to diagnose a heart condition.
Further diagnostic coronary angiography is not routinely indicated after coronary stent implantation. If progression of heart disease is suspected, a stress test will be performed; patients who develop symptoms or show evidence of ischemia in a stress test may undergo diagnostic cardiac re-catheterization. [35]
PPS can also be caused after a trauma, a puncture of the cardiac or pleural structures (such as a bullet or stab wound), after percutaneous coronary intervention (such as stent placement after a myocardial infarction or heart attack), or due to pacemaker or pacemaker wire placement. [1]
Coronary artery disease (CAD), also called coronary heart disease (CHD), or ischemic heart disease (IHD), [13] is a type of heart disease involving the reduction of blood flow to the cardiac muscle due to a build-up of atheromatous plaque in the arteries of the heart. [5] [6] [14] It is the most common of the cardiovascular diseases. [15]

Symptoms of the acute coronary syndromes are similar. [8] The cardinal symptom of critically decreased blood flow to the heart is chest pain, experienced as tightness, pressure, or burning. [9] Localization is most commonly around or over the chest and may radiate or be located to the arm, shoulder, neck, back, upper abdomen, or jaw. [9]
