The effectiveness of therapy for an acute coronary syndrome (ACS) is dependent on patients' quick decision to seek treatment. We surveyed patients' level of knowledge about heart disease and self-perceived risk for a future acute myocardial infarction (AMI) in patients with documented ischemic heart disease. Patients (N = 3522) had ...

We aimed to develop 12-lead electrocardiographic (ECG) models testing ST-elevation criteria with QRST variables and compare their performance with the 80-lead body surface map (BSM) in detection of acute myocardial infarction (AMI). Because the prevalence of non-ST-elevation AMI is increasing worldwide, advances in early ECG detection of AMI are urgently ...

Recent improvements in therapeutic strategies did not prevent left ventricular remodeling (LVR), which remains a common event (30%) after acute myocardial infarction (AMI). We report the use of a systematic approach, based on comparative proteomics, to select circulating biomarkers that may be associated with LVR. We selected 93 patients enrolled ...

Cardiovascular magnetic resonance is considered the standard imaging modality in clinical trials to monitor patients after acute myocardial infarction. However, limited data are available with respect to infarct size, presence and extent of microvascular injury (MVO) and changes over time, in relation to cardiac function in optimally treated patients. In ...

There is debate about whether therapies that reduce mortality in acute myocardial infarction (AMI) will increase the risk for heart failure. In this study, an inception cohort of patients hospitalized with AMIs from April 1, 1994, to March 31, 1999 (without previous diagnoses of heart failure or myocardial infarction), were ...

BACKGROUND: Acute hyperglycaemia has been associated with impaired microvascular function after acute myocardial infarction (AMI), whereas pre-infarction angina (PIA) occurring shortly before the onset of AMI has been shown to reduce microvascular injury after reperfusion. OBJECTIVE: To examine whether acute hyperglycaemia prevents the protective effect of PIA on microvascular function ...

AIM: Predictions of the onset of acute myocardial infarction (AMI) in high risk individuals are of great clinical importance. Among various risk factors, elevated levels of oxidized low density lipoprotein (ox-LDL) in plasma have been shown to reflect unstable coronary plaques. Coronary calcification is a common finding in the elderly, ...
Nijmeijer R - - 2008
BACKGROUND: Secretory type-II phospholipase A(2) (sPLA(2)-II) is a cardiovascular risk marker since higher levels of this acute phase protein imply an increased risk for coronary artery disease. Moreover, it is hypothesized that local activity of sPLA(2)-II in the atherosclerotic plaque facilitates an inflammatory response to induce plaque instability or rupture. ...

The mechanism mediating the development of ventricular arrhythmia (VA) after acute myocardial infarction (AMI) is still uncertain. Thrombin receptor (TR) activation has been proven to be arrhythmogenic in many other situations, and we hypothesize that it may participate in the genesis of post-AMI VA. Using a left coronary artery ligation ...

Oxidative stress has been associated with degenerative diseases such as cardiovascular and neurodegenerative diseases. Acute myocardial infarction (AMI) is the major cause of death among cardiovascular diseases. Inflammation, a major risk factor of AMI, is associated with leukocytic activation, secretion of myeloperoxidase (MPO) and subsequent oxidant generation. It has been ...
