Do statins influence the prognostic impact of non-sustained ventricular tachycardia after ST-elevation myocardial infarction?
After STEMI, only in patients not on statin treatment, the occurrence of NSVT is associated with a significant and marked increase in 1 year mortality.
The congruence of keratoconus classification was very poor of all the techniques tested in our study. This applies to objective measures such as TKC, KMP as well as clinical classification techniques such as Amsler and retinoscopy. Compared to TKC and KMP, retinoscopy underestimates keratoconus stages. In contrast, the performance of binary decisions (normal vs. keratoconus) shows a high sensitivity and specificity. Retinoscopy, however, showed a clear clinical use in confirming the diagnosis of keratoconus.
