Auricular Vagus Stimulation and STEMI

Vagus Nerve StimulationAcute Coronary Syndrome1 more

At the moment, the invasive strategy for the infarct-associated coronary artery in patients with ST-segment elevation myocardial infarction (STEMI) necessary to save the myocardium and reduce the size of the necrosis zone remains the leading one. However, despite the high efficiency of providing medical care to patients with acute coronary syndrome (ACS), there remains a high mortality and disability of this group of patients. In this regard, the search for new drug and non-drug strategies for the treatment of patients with ACS is actively continuing. Over the past decade, it has been shown that transcutaneous vagus nerve stimulation (TENS) has a cardioprotective effect both in chronic heart failure and in coronary heart disease, improves cardiac function, prevents reperfusion injury, weakens myocardial remodeling, increases the effectiveness of defibrillation and reduces the size of a heart attack. One of the methods of noninvasive stimulation of the afferent fibers of the vagus nerve is percutaneous electrical stimulation of the auricular branch of the vagus nerve. However, further studies are needed to determine whether stimulation of the tragus can improve the long-term clinical outcome in this cohort of patients.

Short and Intermediate Term Effect of Dapagliflozin on Left Ventricular Remodeling in Anterior STEMI...

STEMI

Methodology This study will enroll (120) patients presenting with acute anterior STEMI who will undergo early reperfusion presenting at Helwan University Hospitals and Ain Shams University Hospitals. Diagnosis of STEMI will be based on: Sustained ST-segment elevation of at least 1 mm in at least 2 contiguous leads or new/presumably new left bundle branch block, plus >Typical anginal pain, or > diagnostic levels of serum cardiac biomarkers, or > imaging evidence of new loss of viable myocardium or new regional wall motion abnormality. They will be subdivided into two (2) groups according to Dapagliflozin intake into: - Group A: Patients with diabetes mellitus (DM) (60) patients, they will be further subdivided into 2 subgroups: Group A1: 30 patients will receive Dapagliflozin in addition to standard anti-ischemic and anti-diabetic treatment. Group A2: 30 patients will receive standard anti-ischemic and antidiabetic treatment (Dapagliflozin not included). - Group B: Patients without DM (60) patients, subdivided to 2 subgroups: Group B1: 30 patients will receive standard anti-ischemic treatment. Group B2: 30 patients will receiv up e standard anti-ischemic treatment and Dapagliflozin. Methodology in details: The study patients will undergo early reperfusion according to the recent practice guidelines and the local hospital policy in managing ST elevation MI patients. Echocardiography will be performed twice: within 48 hours of admission and 3 months following the index event. Management: Twelve-lead electrocardiogram will be recorded at baseline and 30-min post-procedure. The ST-segment changes will be evaluated in the single lead with the most prominent ST-segment elevation before intervention. The ST-segment elevation will be measured to the nearest 0.5 mm at 60 ms after the J point. Significant ST segment resolution (STR) is defined as a reduction in ST-segment elevation of 50% after 30 min of infarct artery recanalization. Immediately before the procedure, patients will receive aspirin (300 mg), ticagrelor (180 mg) or clopidogrel (600 mg) depending on availability. Adjunctive pharmacological treatment during the procedure will include: Unfractionated heparin as an initial bolus of 70 U/kg and additional boluses during the procedure to achieve an activated clotting time of 250 to 350 s (200 to 250 s if Glycoprotein IIb/IIIa (GPIIb/IIIa) antagonist is used). Heparin will be discontinued at the end of percutaneous coronary intervention. The use of a GPIIb/IIIa antagonist during the procedure, primary PCI technique, indications, and methods of thrombectomy if indicated will be done under the regulations of the local hospital policy and the most recent practice guidelines.

Efficacy and Safety of a Half-dose Bolus of r-SAK Prior to Primary PCI in ST-elevation Myocardial...

ST Elevation Myocardial Infarction

As an effective treatment for acute ST-segment elevation myocardial infarction (STEMI), early reperfusion may reduce the infarct size and improve the prognosis of patients. However, it remains uncertain whether adjunctive thrombolytic therapy administered immediately prior to primary percutaneous coronary intervention (PCI) improves outcomes in patients undergoing the procedure within 120 minutes. In this investigator-initiated, prospective, multi-center, randomized, double-blind, placebo-controlled trial, subjects meeting the inclusion/exclusion criteria should be randomly assigned 1:1 to the trial group (r-SAK) or the control group (placebo). The risk of major adverse cardiovascular events within 90 days will be observed.

A Polypill for Secondary Prevention of Ischemic Heart Disease

Acute Myocardial InfarctionST Elevation Myocardial Infarction1 more

Cardiovascular diseases (CVD) are the leading cause of mortality and morbidity worldwide. The most important aspect of CVD secondary prevention is adherence to guideline-indicated pharmacological therapy which globally remains low. In previous studies, a Polypill containing fixed dose combination of essential drugs have improved patient adherence to these drugs. The effect of such a strategy on pharmacological therapy uptake, cost-effectiveness, and CVD recurrence in our setting will be assessed in this study. Participants hospitalized in three referral hospitals in Isfahan, Iran because of an acute myocardial infarction (MI) (ST elevation MI (STEMI) or non-ST elevation MI (NSTEMI)) will be randomized to either receiving Polypill or usual care after MI. Patient recruitment will be carried out at the time of patient discharge from the hospitals.

ST-elevation Myocardial Infarction (STEMI)

This is a Phase 3 prospective, blinded, randomized, placebo controlled, international multicenter study. Subjects with STEMI will be enrolled in the ambulance if they meet all eligibility criteria. These subjects will be evaluated by (para)medics who transport the subjects to the participating hospitals in Europe and North America. Hospitals and ambulance services with experience in ambulance studies will be selected. Each subject will receive a single subcutaneous injection containing either zalunfiban Dose 1 (0.110 mg/kg) or zalunfiban Dose 2 (0.130 mg/kg) or placebo

Intravascular Ultrasound Versus Angiography Guided Drug-coated Balloon Treatment for STEMI Patients:a...

STEMI

Objectives: The present study aimed to investigate the difference in late luminal loss (LLL) at 9-month after drug-coated balloon (DCB) treatment with intravascular ultrasound (IVUS) versus angiography for ST-segment elevated myocardial infarction (STEMI)patients. Background: In primary percutaneous coronary intervention for STEMI, DCB angioplasty has proved to be a safe and feasible strategy. Compare with angiography guidance, IVUS-guided PCI significantly improve clinical outcome. With IVUS guidance, STEMI patients undergo DCB angioplasty might have be beneficial results. Methods: A total of 208 STEMI patients who required DCB treatment were randomly assigned either an IVUS guidance and angiography guidance group. The primary endpoint was late luminal loss at 9-month. Stent thrombosis (ST) was the safety endpoint.

It is planned to include 200 patients hospitalized with primary myocardial infarction with and without ST segment elevation (STEMI or NSTEMI) in combination with COVID-19 within the first 15 days from the disease onset. The total follow-up period is 96 weeks. Hypotheses: An integrated approach in assessing myocardial contractility, regulation of the heart and the structural and functional state of arteries will make it possible to more accurately assess the heart pumping function; explain the mechanisms of the relationship between left ventricular (LV) contractile function and its volumetric indices; to study the mechanisms of ventriculo-arterial coupling and the influence of autonomic regulation, the role of markers of the sudden cardiac death (late ventricular potentials, pathological turbulence of the heart rate, dispersion of the QT interval). In patients who have had myocardial infarction in combination with the new coronavirus infection SARS-CoV-2 (COVID-19), long-term highly effective lipid-lowering therapy, regardless of the drugs prescribed, has an antiarrhythmic effect and has a beneficial effect on the autonomic regulation of the heart rate. Highly effective lipid-lowering therapy leads to an improvement in LV contractility and structural and functional properties of the large arteries.
