Relationship between ECG-derived T-wave amplitude and T/R ratio and Syntax score in patients with acute non-st segment elevation myocardial infarction.

Objectives And Background: Our objective was to determine the diagnostic significance of a low T-wave amplitude (TWA) and T/R ratio, defined as the amplitude ratio between the T waves and the R waves, in patients with acute non-ST elevation myocardial infarction (ANSTEMI). Syntax score (SS) shows the extension of coronary artery disease. Previously, low TWA and T/R ratios were demonstrated to be inversely proportional to the risk of sudden cardiac arrest in different cardiac disease conditions.

Comparative effects of high-dose atorvastatin versus rosuvastatin on lipid parameters, oxidized low-density lipoprotein, and proprotein convertase subtilisin kexin 9 in acute coronary syndrome.

Aim: Current guidelines recommend administration of high-dose statins in acute coronary syndrome (ACS). It has been reported that statins upregulate proprotein convertase subtilisin kexin 9 (PCSK9) mRNA expression and increase circulating PCSK9 levels. We aimed to compare the effects of high-dose atorvastatin and rosuvastatin on serum oxidized low-density lipoprotein (oxidized-LDL) and PCSK9 levels in statin-naive patients with ACS.
