Coronary restenoses is a medical term used to describe the narrowing or blockage of a coronary artery that has previously been treated. The correct pronunciation of this word is kɔrənɛri rɛstɪnoʊzɪz. The first syllable is pronounced with a long "o" sound as in "door," while the second syllable has a short "u" sound like in "butter." The stress falls on the second syllable "no," which is pronounced with a long "o" sound as in "go." The "s" at the end of the word is pronounced as "z."
Coronary restenosis refers to the narrowing or constriction of a previously treated coronary artery, resulting in reduced blood flow to the heart muscles. It occurs as a consequence of the healing process that takes place after a coronary intervention procedure, such as angioplasty or stent placement, which are performed to treat blocked or narrowed coronary arteries.
Following a coronary intervention, the damaged artery undergoes a healing response where cells start to grow and cover the area where the intervention was performed. However, in some cases, this healing response leads to an excessive growth of cells, resulting in the re-narrowing of the treated artery. This abnormal growth is referred to as restenosis.
Coronary restenosis typically occurs within the first few months after the coronary intervention procedure, although it can also occur several years later. It may be asymptomatic at first but can lead to symptoms of reduced blood flow to the heart, such as chest pain (angina), shortness of breath, fatigue, or even a heart attack if the narrowing becomes severe.
The treatment of coronary restenosis often involves repeat interventions, such as balloon angioplasty or the placement of a new stent, to widen the narrowed artery and restore proper blood flow. Additional medications may also be prescribed to prevent further narrowing and reduce the risk of future restenoses.
The word "coronary restenosis" is composed of two main elements: "coronary" and "restenosis".
The term "coronary" refers to the coronary arteries, which are the blood vessels that supply oxygen-rich blood to the heart muscles. The word "coronary" is derived from the Latin word "corona", meaning "crown", due to the heart's position in the chest and the arrangement of the blood vessels resembling a crown.
"Restenosis" is a medical term used to describe the re-narrowing or recurrence of a blood vessel after treatment, such as angioplasty or stenting. It is compounded from two Latin roots: "re", meaning "again" or "back", and "stenosis", meaning "narrowing" or "constriction".
