2014-07-23 21:11:22 | BioPortfolio

Summary

Continuing high dose clopidogrel treatment after elective PCI decreased adverse cardiac events in patients with clopidogrel resistance

Description

Aim:

Primary objective:

- To evaluate the effect of continuing high dose clopidogrel treatment on adverse cardiac events after elective PCI in patients with clopidogrel resistance

Secondary objective:

- To evaluate the effect of continuing high dose clopidogrel treatment on adverse cardiac events after elective PCI

- To evaluate the effect of continuing high dose clopidogrel treatment on bleeding complications after elective PCI

- To evaluate the clinical effect of VerifyNow which use as a clopidogrel resistance kit.

Study central:

Bursa Postgraduate Hospital, Cardiology Clinic

Study population:

we planned to enrol 180 patients. 50% of patients without clopidogrel resistance (control group: 90 patients) 50% have clopidogrel resistance. Than we randomise the patients (with clopidogrel resistance) in two groups (group 1:45 patients (75mg/day), group 2:45 patients (150mg/day))

inclusion criteria:

- The patients; who have planned elective PCI and have had written informed consent for participation to study.

- Age>18 year-old,

- The native coronary artery;lesion with narrowing >=70%

Exclusion criteria:

- Patients have allergy for ASA, Clopidogrel and heparin

- Patients who performed primary PCI

- Patients with acute coronary syndrome

- Patients with have a history of PCI and use clopidogrel

- Patients on warfarin therapy

- Patients who have bleeding diathesis, or have high risk for bleeding.

Study works:

- Write case report form for all patients

- Control for inclusion criteria.

- Evaluate the clopidogrel and ASA resistance with VerifyNow kit. Than randomised the patients.

- Demographic data (age, gender)

- Height, weight, BMI and GFR

- Risk factors

- laboratory data (biochemical and hematologic)

- Medication history

- Echocardiographic data

- Angiographic data

- PCI data(vessel diameter, stent diameter, lesion and stent length, performed PTCA or not, etc)

- Note complication (MACE, bleeding, hematoma etc)

4 weeks later note the first control data and re assess the clopidogrel resistance with VerifyNow kit in patients groups 1 and 2.

Six months later note the second control data.

Medical and Biotech [MESH] Definitions

Surgical therapy of ischemic coronary artery disease achieved by grafting a section of saphenous vein, internal mammary artery, or other substitute between the aorta and the obstructed coronary artery distal to the obstructive lesion.

Direct myocardial revascularization in which the internal mammary artery is anastomosed to the right coronary artery, circumflex artery, or anterior descending coronary artery. The internal mammary artery is the most frequent choice, especially for a single graft, for coronary artery bypass surgery.

A complication of INTERNAL MAMMARY-CORONARY ARTERY ANASTOMOSIS whereby an occlusion or stenosis of the proximal SUBCLAVIAN ARTERY causes a reversal of the blood flow away from the CORONARY CIRCULATION, through the grafted INTERNAL MAMMARY ARTERY (internal thoracic artery), and back to the distal subclavian distribution.

A congenital coronary vessel anomaly in which the left main CORONARY ARTERY originates from the PULMONARY ARTERY instead of from AORTA. The congenital heart defect typically results in coronary artery FISTULA; LEFT-SIDED HEART FAILURE and MITRAL VALVE INSUFFICIENCY during the first months of life.

Pathological processes of CORONARY ARTERIES that may derive from a congenital abnormality, atherosclerotic, or non-atherosclerotic cause.
