Cardiac rehabilitation programme as a non-pharmacological platelet inhibitory tool in acute coronary syndrome survivors.

Background Acute coronary syndrome is associated with platelet hyperactivity, which in its persistent form, promotes recurrent thrombotic events. Complex cardiac rehabilitation after acute coronary syndrome improves clinical outcome; however, its effect on platelet hyperactivity is unknown. Design and methods We enrolled 84 acute coronary syndrome patients on dual antiplatelet therapy, who underwent a new complex cardiac rehabilitation programme (NovaCord physiotherapy, lifestyle counselling, strict diet, stress management and regular coaching) and 51 control acute coronary syndrome patients with traditional cardiac rehabilitation.

Alternative complement pathway activation during invasive coronary procedures in acute myocardial infarction and stable angina pectoris.

The effect of invasive percutaneous coronary procedures on complement activation has not been elucidated. We enrolled stable angina patients with elective percutaneous coronary intervention (SA-PCI, n=24), diagnostic coronary angiography (CA, n=52) and 23 patients with ST segment elevation myocardial infarction and primary PCI (STEMI-PCI). Complement activation products (C1rC1sC1inh, C3bBbP and SC5b-9) were measured on admission, 6 and 24h after coronary procedures.

The lack of aspirin resistance in patients with coronary artery disease.

Background: Aspirin resistance established by different laboratory methods is still a debated problem. Using COX1 specific methods no aspirin resistance was detected among healthy volunteers. Here we tested the effect of chronic aspirin treatment on platelets from patients with stable coronary artery disease.

Predictors of high on-clopidogrel platelet reactivity in patients with acute coronary syndrome.

High on-clopidogrel platelet reactivity (HPR) is a predictor of ischemic events after percutaneous coronary intervention. We conducted a prospective cohort study to identify variables related to HPR in acute coronary syndrome patients who are at high thrombotic risk. We enrolled 463 patients undergoing urgent coronary angiography.

High on clopidogrel treatment platelet reactivity is frequent in acute and rare in elective stenting and can be functionally overcome by switch of therapy.

Unlabelled: The benefit of adjusted antiplatelet therapy in patients with myocardial infarction after primary percutaneous coronary intervention is not well elucidated. We aimed to identify patients with high on treatment platelet reactivity and to gradually adjust antiplatelet therapy.

Materials And Methods: We enrolled 133 acute myocardial infarction and 67 stable angina patients undergoing intracoronary stenting into our study.

Elevated C1rC1sC1inh levels independently predict atherosclerotic coronary heart disease.

Unlabelled: Clinical studies as well as animal models emphasized the importance of the complement system in the pathogenesis of coronary atherosclerosis and cardiovascular diseases. Our aim was to examine the extent and clinical implication of complement system activation in patients with stable atherosclerotic coronary heart disease (ACHD). Seventy-six patients with stable angina pectoris (SAP) scheduled for elective coronary angiography were enrolled into the study.
