Filter by:The aim of this study is to examine the effect of secondary prevention education given to individuals after acute myocardial infarction on physiological parameters, anxiety and quality of life.
Patients with STEMI and multivessel disease in whom the culprit lesion has been successfully revascularized during prmimary PCI, will be randomized to in-hospital or after-discharge complete revascularization. The purpose of this study is to evaluate the impact of these two different strategies in terms of hospital stay.
Elderly individuals are increasingly represented among patients with acute coronary syndrome (ACS). Dual antiplatelet therapy (DAPT) with aspirin and an oral P2Y12 receptor inhibitor has an established role in the prevention of atherothrombotic events in ACS setting. However, DAPT in older patients is challenged by a concurrent heightened risk of ischemia and bleeding. Although guidelines recommend DAPT with aspirin and ticagrelor for elderly patients with ACS, clopidogrel, a less potent antiplatelet agent, continues to be used in more than one third of ACS patients with elderly status being the strongest predictor of undertreatment. A lower dose of ticagrelor may represent an alternative to the standard dose by conferring a similar efficacy and, potentially, a better safety profile. Our prospective, randomized, double-blind, crossover trial will test the hypothesis that a lower dose of ticagrelor provides similar antiplatelet effects compared with a standard dose among elderly patients with ACS. The main aim of the trial is to determine the pharmacodynamic and pharmacokinetic profile of ticagrelor 60 mg twice daily versus ticagrelor 90 mg twice daily among elderly patients with ACS undergoing PCI. This will be a prospective, randomized (1:1 ratio), non-inferiority, open-label, crossover trial to evaluate the level of platelet inhibition achieved with a low-dose of ticagrelor (60 mg twice daily) versus a standard dose of ticagrelor (90 mg twice daily) among elderly patients with ACS undergoing PCI.
Contrast induced acute kidney injury has commonly been referred to as contrast induced nephropathy (CIN) defined as an increase in serum creatinine ≥25% or ≥0.5 mg/dl from baseline within 48-72 hours with peak incidence 2-5 days after contrast exposure.1. CIN, Which can potentially lead to acute kidney failure or mortality, is still common among hospitalized patients. In addition, contrast medium exposure may lead to long-term outcomes such as dialysis-requiring renal failure or death.2. The incidence of CIN ranges from 7% to 25% in different population subgroups based on the risk status. Hence, risk stratification has an important bearing in order to provide the appropriate preventive therapies to those high-risk individuals before and after contrast media exposure.3. In the past, several risk prediction models have been proposed to envisage the CIN incidence. Mehran proposed a scoring system comprising eight variables which correlated well with the CIN risk. Despite having a fair degree of accuracy; complexity was one of the major limitations of such models.4 .Most predictive models for contrast induced nephropathy in clinical use have modest ability, and are only applied to patients receiving contrast for coronary angiography. Further research is needed to develop models that can better inform patient centered decision making, as well as improve the use of preventive strategies for contrast induced nephropathy.5. ST-elevation myocardial infarction (STEMI) is a clinical syndrome defined by characteristic symptoms of myocardial ischemia in association with persistent electrocardiographic ST elevation (STE) and subsequent release of biomarkers of myocardial necrosis.1 STE is the single best immediately available surrogate marker for detecting acute complete coronary artery occlusion, denoting a significant region of injured myocardium at imminent risk of irreversible infarction, requiring immediate reperfusion therapy.6. Primary percutaneous coronary intervention(PCI) if performed in a timely fashion is the recommended modality of reperfusion in STEMI cases as per guidelines [ACC-ESC-STEMI & revascularization]. Frequently, baseline kidney functions are unknown, nevertheless, to maximize salvaging myocardial tissue for STEMI patients; immediate reperfusion is prioritized over awaiting tests results. Considering the systemic inflammatory response associated with STEMI and that commonly due to severe pain and agony, those patients are not properly hydrated, added to higher prevalence of MI-related myocardial dysfunction and heart failure than in elective cases, primary PCI for STEMI cases might have higher risk than usual of CIN.7,8. The CHA2DS2-VASC score is traditionally used for embolic risk stratification in atrial fibrillation (AF) patients and includes the following variables: congestive heart failure (CHF), hypertension, age ≥75 years, diabetes mellitus (DM), previous stroke, vascular disease, age 65 to 74 years and sex.9. The CHA2DS2-VASC score has been reported recently to have a prognostic utility to predict adverse clinical outcomes in patients with acute coronary syndrome (ACS), regardless of having AF.10. The CHA2DS2VASC score is practical and easy to memorize and apply in STEMI cases, however, strong evidence to validate its prognostic value in predicting CIN in the setting acute STEMI is lacking.
The actual evidence is solid about the use of de SGLT2-inhibitors in wide spectrum of cardiorenal targets, which has been shown in a great amount of randomized clinical trials compared with placebo. At present it must be taken into account as first line treatment in patients with DM2, even their security profile has allowed the use in patients without diagnosis of DM2, since they have be shown a beneficial cardioprotect effects. Most studies support they use in patients with high cardiovascular risk, nevertheless, their use in patients with recent diagnosis of ischemic hearth disease its limited, being the latter entity the most frequent etiology found in patients who develop chronic hearth failure either as part of heart attack or unstable angina.
Cipherome's Lighthouse is a clinical decision support tool that incorporates a patient's pharmacogenetic information to determine therapeutic strategy, including determining appropriate dosage or assessing the likelihood of toxicity of a therapeutic regimen.
A total of 100 patients with ST-elevation myocardial infarction (STEMI) presenting slow-flow after primary-percutaneous coronary intervention (PPCI) will be randomized to pharmacologic treatment with hyperemic drugs versus flow-mediated hyperemia.
This is an interventional, prospective, multicenter study (5 IRCCS hospitals belonging to the Italian Cardiology Network) in patients with STEMI treated with successful primary PCI to assess the ability of coronary physiology parameters measured soon after recanalization to predict myocardial tissue characterization assessed with cardiac magnetic resonance (CMR) within a week of the acute event. Furthermore, patients will be followed up for a period of 12 months to assess the incidence of major adverse cardiovascular events (death, death from cardiovascular causes, re-infarction, new coronary revascularization interventions, development of heart failure) based on their stratification according to coronary physiology parameters.
This study is being done to determine if taking an electrocardiogram (ECG) by a portable device (SmartHeart) followed by a phone call will improve patient outcomes by early recognition of abnormalities and decrease emergency room visits and hospital readmissions compared to standard therapy alone.
The objective of this study was to assess the impact of a nursing intervention on therapeutic adherence in elderly patients after acute myocardial infarction compared to a control group
