hsTn I

Additional risk stratification may provide more aggressive and focalized preventive treatment to high-risk hypertensive patients according to the Japanese hypertension guidelines. We prospectively investigated the predictive value of high-sensitivity troponin I (hsTnI), both independently and in combination with N-terminal pro-B-type natriuretic peptide (NT-proBNP), for incident heart failure (HF) in high-risk hypertensive patients with preserved left ventricular ejection fraction (LVEF). Baseline hsTnI and NT-proBNP levels and echocardiography data were obtained for 493 Japanese hypertensive outpatients (mean age, 68...

OBJECTIVE: To validate the National Institute for Health and Care Excellence (NICE) recommended algorithms for high-sensitivity troponin (hsTn) assays in adults presenting with chest pain. METHODS: International post hoc analysis of three prospective, observational studies from tertiary hospital emergency departments. The primary endpoint was cardiac death or acute myocardial infarction (AMI) within 24 hours of presentation, and the secondary endpoint was major adverse cardiac events (MACE) at 30 days...

The evaluation of patients presenting to the emergency department with suspected acute coronary syndrome (ACS) remains a clinical challenge. The traditional assessment includes clinical risk assessment based on cardiovascular risk factors with serial electrocardiograms and cardiac troponin measurements, often followed by advanced cardiac testing as inpatient or outpatient (i.e. stress testing, imaging). Despite this costly and lengthy work-up, there is a non-negligible rate of missed ACS with an increased risk of death...

OBJECTIVES: This study compared diagnostic accuracy of conventional troponin/traditional coronary artery disease (CAD) assessment and highly sensitive troponin (hsTn) I/advanced CAD assessment for acute coronary syndrome (ACS) during the index hospitalization. BACKGROUND: hsTnI and advanced assessment of CAD using coronary computed tomography angiography (CTA) are promising candidates to improve the accuracy of emergency department evaluation of patients with suspected ACS...

Highly sensitive troponin (hsTn) assays may predict cardiovascular (CV) events and left ventricular (LV) remodeling in patients with heart failure (HF). In this study, 99 subjects with LV systolic dysfunction (LVSD) were followed 10 ± 3 months with serial measurement of hsTnI by a novel method. hsTnI was detectable in all subjects and was above the 99th percentile of a normal population in 56.7 %. Supramedian baseline hsTnI concentration was associated with higher-risk clinical features and shorter time-to-first event (p = 0...

HYPOTHESIS: We examined the hypothesis that a specific myocardial injury marker, namely high sensitive cardiac troponin-I (HsTn-I), is elevated in patients with slow coronary flow (SCF) pattern. AIM: To examine the above hypothesis by studying a group of patients who had undergone coronary angiography for the detection of their chest pain aetiology with SCF pattern despite an angiographically normal coronary arteriogram. METHODS: We evaluated and performed coronary angiography (CAG) of 97 patients with chest discomfort...
