[Myocardial ischemia in general medicine and the revolution of coronary stents].

Since Gruentizg's first percutaneous transluminal ballon angioplasty in 1977 in Zurich, percuta. neous coronary intervention evolved significantly in order to overcome the numerous associated complications of each technique. Bare-metal stents (BMS) made their initial appearance followed by three generations of drug-eluting stents (DES).

The contribution of 99mTc-pyrophosphate tomoscintigraphy in the evaluation of necrotic myocardial lesions.

Diagnostic contribution of Conventional Planar Scintigraphy (CPSc) and Single Photon Emission Computed Tomoscintigraphy (SPECT), using 99mTc-Pyrophosphate (99mTc-PYP), have been compared in 49 patients with either transmural (T.I., N = 40), or non-transmural (N.
