Stent migration: Stent may move causing symptoms to recur or lead to other complications. Stent obstruction: Blockage can occur, repeating symptoms or other complications. Stent related pain: Chest or throat pain may occur after the procedure; requiring additional treatment or adjustment of the stent.
Affected people usually have repeated episodes of unexplained (e.g., in the absence of exertion and occurring at sleep or in the early morning hours) chest pain, tightness in throat, chest pressure, light-headedness, excessive sweating, and/or reduced exercise tolerance that, unlike atherosclerosis-related angina, typically does not progress to ...
Coronary vasospasm classically produces chest pain at rest, also known as variant angina (vasospastic angina or Prinzmetal's angina). [5] Chest pain is more common at certain times of the day, usually from late night to early morning. [6] These episodes can be accompanied by nausea, vomiting, cold sweating, and even syncope.
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 ...
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.
There are many chest pain causes (including a heart attack) that can lead to similar types of discomfort, and it can be really tricky to know what you're actually dealing with. 11 causes of chest ...
In addition to intervascular stents, he also developed the first stent-supported porcine valve that can be implanted transcutaneously in 7 minutes, eliminating open-heart surgery. [ 37 ] In development are stents with biocompatible surface coatings which do not elute drugs, and also absorbable stents (metal or polymer).
As with any procedure involving the heart, complications can sometimes, though rarely, cause death. The mortality rate during angioplasty is 1.2%. [17] Sometimes chest pain can occur during angioplasty because the balloon briefly blocks off the blood supply to the heart. The risk of complications is higher in: [18] People aged 65 and older
