Filter by:Patients with ischemic heart disease often report multiple symptoms, including angina and palpitations. Ranolazine has antiarrhythmic effects which are largely a result of the drug's effect on multiple ion channels. It remains unknown, however, whether the favorable effects of ranolazine on symptoms and arrhythmias are maintained over time. Aim of this study is to test the hypothesis that chronic treatment with ranolazine can improve the symptomatic status of patients with ischemic heart disease by reducing the occurrence of palpitations.
The main purpose of this study is to examine whether changes in biomarkers during exercise are related to coronary artery disease demonstrated by coronary angiography or echocardiography.
It is the aim of the study to compare the effects of 6 weeks of either high-intensity interval training (HIT; carried out at correctly assessed 85-95% of maximal heart rate), pyramid, or continuous endurance training, on changes of physical exercise capacity in cardiac patients. The three exercise arms (isocaloric) are composed as follows: Endurance training (n=15): 31min at 65-75% HRmax; HIT (n=15): 4x4min intervals at 85-95% HRmax divided by 3x3min of active recovery at 60-70% HRmax, making it a total of 25min; Pyramids (n=15): One Pyramid consists of 8 one-minute blocks. Those are grouped starting with one block of 70-75% HRmax, followed by one block at 75-80% HRmax and another one at 80-85% HRmax. The top of the pyramid are 2 blocks of 85-90% HRmax. Intensity is lowered afterwards with one block at 80-85% HRmax, followed by one block at 75-80% HRmax and last one at 70-75% HRmax. Two more pyramids follow, each divided by 2min of active recovery at 65-70% HRmax, making it a total of 28min. All protocols are initiated by 5min of warm-up and end with 5min of cool-down, both at 60-70% HRpeak. Primary Outcome: Individual maximum power output in watt (Pmax). Secondary Outcome: Change of power output in watt at lactate thresholds at 2 and 4 mmol/l.
Patients who undergo urgent/emergency coronary angiography can not receive any preventive treatment of contrast induced nephropathy. We tested the hypothesis that Neutrophil gelatinase-associated lipocalin (NGAL), a new biomarker predictive for AKI, allows early and effective treatment of contrast induced nephropathy in patients with urgent/emergency coronary angiography
It has previously been shown that pretreatment with ranolazine 1,000 mg twice daily for 7 days can significantly reduce procedural myocardial injury in elective percutaneous coronary intervention (PCI). The investigators tested the hypothesis that twice overnight high-dose ranolazine loading before PCI can reduce the peri-procedural myocardial ischemic damage similarly to long-term pre-treatment with standard doses.
No previous study has assessed the potential of ranolazine to interfere with levels of platelet reactivity in patients with coronary artery disease who are treated with dual antiplatelet therapy. Aim of this study is to compare the pharmacodynamic effects of maintenance doses of ranolazine versus amlodipine on platelet reactivity in patients with coronary artery disease who are treated with dual antiplatelet therapy.
Pharmacologic alternatives in statin-intolerant patients include ezetimibe and nutraceuticals (i.e. compounds derived from foods with cholesterol lowering actions). The investigators will compare the efficacy and tolerability of ezetimibe versus a nutraceutical-based protocol in statin-intolerant patients treated with percutaneous coronary intervention.
The Provisional Heparin TherApy on Radial Artery Occlusion after transradial coronary angiography and patent Hemostasis (PHARAOH) study compares the strategy of standard a-priori heparin use in patients undergoing transradial coronary angiography to a strategy of provisional heparin administration only if patent hemostasis is not achievable.
This is a multi-center, randomized, study to compare the efficacy of zotarolimus-eluting stent (Resolute Integrity or Resolute Onyx stent) or everolimus-eluting stent (Xience Prime or Xience Xpedition or Xience Alpine stent) for very long coronary lesions.
The aim of the present trial is to assess the efficacy of the standalone use of SeQuent(R) Please coated balloon compared to a bare metal stent (BMS) in patients with NSTEMI.
