Respected user, hi I evaluated your query thoroughly.
*No.of stents are dependent on the no.of blocked arteries.
*Inability to put stent in particular
artery must be because of high level of
narrowing of lumen & inability to negitiate the stent through it , also if
other cardiac /
anesthetic point of view may be postpone for betterment of
patient
*Arterial blocking depend on many factors including patient`s
cholesterol levels, life style , medications,
stress levels, food habits, comorbid
conditions, smoking/alcohol consumption , mobility of patient & so on.
Hope this clears your query .
