Acute ST segment elevation is regarded generally as the sine qua non of evolving Q wave myocardial infarction (MI) because such electrocardiographic (ECG) injury is believed to be a marker of transmural ischemia and a forerunner of transmural necrosis. Alternatively, ST segment depression with or without T wave inversion is viewed as the dominant ECG feature of non-Q wave MI. However, this hypo...

BACKGROUND Elevation of cardiac biomarkers after coronary angioplasty (percutaneous coronary intervention [PCI]) reflects periprocedural myocardial damage and is associated with adverse cardiac events. We assessed whether periprocedural myocardial damage that occurs despite successful PCI could be rapidly and easily identified by intracoronary ST-segment recording with the use of a catheter gui...

Zero-point vibrationally averaged (rg 0 ) structures were computed at the PBE0/SDD/631G* level for the [Pt 35 Cln 37 Cl5-n(H2 18 O)]  (n=0-5), cis-Pt 35 Cln 37 Cl(4-n)(H2 18 O)(H2 16 O) (n=0-4), fac-[Pt 35 Cln 37 Cl(3-n)(H2 18 O)(H2 16 O)2]  (n=0-3), [Pt 35 Cln 37 Cl5-n( 16/18 OH)] 2 (n=0-5), cis-[Pt 35 Cln 37 Cl(4-n)( 16/18 OH)2] 2(n=0-4), fac-[Pt 35 Cln 37 Cl(3-n)( 16/18 OH)3]  (n=0-3), ...

results prediction of the rca as culprit lesion using tierala's algorithm was 86% sensitive and 50% specific. prediction of lcx occlusion based on st-elevation ≥ 1 mm in v6 was 87% specific (p = 0.005). sum of st elevation in leads v5 and v6 more than 2.5 mm, was a good marker of lcx prediction (p = 0.044). st-elevation in v4r was 48% sensitive and 89% specific for rca prediction (p = 0.004). w...

The values of the parameters r, t, St, T , and K used to price a call option via the Black-Scholes formula can be easily obtained from market data. Estimating the volatility coefficient σ can be a more difficult task, and several estimation methods are considered in this section with some examples of how the Black-Scholes formula can be fitted to market data. We cover the historical, implied, a...
