Laboratory data are critical to analyzing and improving clinical quality. In the setting of residual use of creatine kinase M and B isoenzyme testing for myocardial infarction, we assessed disease outcomes of discordant creatine kinase M and B isoenzyme +/troponin I (-) test pairs in order to address anticipated clinician concerns about potential loss of case-finding sensitivity following proposed discontinuation of routine creatine kinase and creatine kinase M and B isoenzyme testing. Time-sequenced interventions were introduced...

The primary aim of this study was to find the potential modulatory roles of quercetin (QUE) against Adriamycin (ADR)-induced cardiotoxicity. A total of 50 rats were assigned to five groups: a control group, an ADR-treated group, a QUE-treated group, a prophylaxis-cotreated group, and a therapeutic-cotreated group, respectively. QUE exhibited a significant cardioprotective effect, particularly, when it was administered prior to and concurrently with ADR treatment (prophylaxis-cotreated group). This effect was biochemically evident by the significant decreases in the serum levels of myocardial injury biomarkers such as troponin, creatine kinase-myocardium bound, and creatine phosphokinase...

Patients with chronic obstructive pulmonary disease (COPD) have a high risk of mortality after acute ST-segment elevation myocardial infarction (STEMI). We compared STEMI patients with versus without COPD in terms of infarct size and left ventricular (LV) systolic function using advanced 2-dimensional speckle tracking echocardiography. Of 1,750 patients with STEMI (mean age 61 ± 12 years, 76% male), 133 (7.6%) had COPD. With transthoracic echocardiography, left ventricular ejection fraction (LVEF) and wall motion score index were measured...

The Valve Academic Research Consortium-2 recommends cutoff levels of cardiac troponin of >15 and of creatine kinase MB (CKMB) of >5 of the upper limit of normal (ULN) as markers of periprocedural myocardial infarction. We aimed to evaluate the correlation of these cutoffs with the survival rate in patients who underwent transcatheter aortic valve implantation (TAVI) through the femoral access. Patients who underwent TAVI were classified according to the postprocedural peak marker level of >15 and >5 ULN for troponin and CKMB, respectively...

RATIONALE: Following prolonged endurance events such as marathons, elevated levels of cardiospecific biomarkers are commonly reported. Although transiently raised levels are generally not considered to indicate clinical myocardial damage, comprehension of this phenomenon remains incomplete. The popularity of high-intensity interval training highlights a paucity of research measuring cardiac biomarker response to this type of exercise. This a posteriori case report discusses the elevation of cardiac troponins (cTn) associated with short interval, high-intensity exercise...

BACKGROUND: Chronic hypobaric hypoxia (cHH) mediated cardiac insufficiencies are associated with pathological damage. Sustained redox stress and work load are major causative agents of cardiac insufficiencies under cHH. Despite the advancements made in pharmacological (anti-oxidants, vasodilators) and non-pharmacological therapeutics (acclimatization strategies and schedules), only partial success has been achieved in improving cardiac acclimatization to cHH. This necessitates the need for potent combinatorial therapies to improve cardiac acclimatization at high altitudes...

BACKGROUND: Ischemia-reperfusion (I/R) injury in ST-segment elevation myocardial infarction (STEMI) significantly contributes to overall myocardial damage. As a consequence of I/R injury in the heart, the high-temperature requirement protein A2 (HtrA2) is released from the mitochondrial intermembrane space of cardiomyocytes to the cytoplasm, whereupon it induces apoptosis. METHODS: Serum was obtained from STEMI (n=37), non-ST-segment elevation myocardial infarction (NSTEMI) (n=20), stable coronary artery disease (CAD) (n=17) and patients with CAD excluded (n=9)...

Phosphorylated proteins in ovine muscle induced by salt curing were well investigated. Ten topside muscles of crossbred sheep were ground, mixed and divided into two groups, which were cured for 16h with 0% and 3% NaCl, respectively. Muscle proteins of two cured groups were analyzed by two-dimensional electrophoresis coupled with Pro-Q Diamond and SYPRO Ruby staining. The differential phosphorylated proteins were determined using LC-MS/MS and the UniProt database. Ten different phosphoproteins (>1.5 fold) induced by salting were identified, including triosephosphate isomerase, glycogen phosphorylase, creatine kinase M-type, myoglobin, troponin T fast skeletal muscle type, actin, myosin light chain 1/3, tropomyosin beta chain, etc...
