Heart patients with persistent or recurrent post-stent chest pain present “an unmet clinical need”, according to the European Journal of Cardiology.
Do Stents Make You Feel Better?
Dr. Paddy Barrett
DECEMBER 5, 2023
The logic of stenting obstructed coronary arteries is simple. A stent unblocks the artery. Subscribe now Stenting stable coronary artery disease has not been convincingly proven to reduce the risk of future heart attacks or death 1. But coronary stenting is not the only way to reduce symptoms of angina.

The commonest causes of MINOCA include: atherosclerotic causes such as plaque rupture or erosion with spontaneous thrombolysis, and non-atherosclerotic causes such as coronary vasospasm (sometimes called variant angina or Prinzmetal's angina), coronary embolism or thrombosis, possibly microvascular dysfunction.
