Trhombus Aspiration in Hyperglycemic ST-elevation myocardiAl InfarcTIon (TAHITI)

Trhombus Aspiration in Hyperglycemic ST-elevation myocardiAl InfarcTIon (STEMI) Patients: 1-year Follow-up of the Prospective Randomised TAHITI Study

Background. Patients with ST-Elevation Myocardial Infarction (STEMI) and hyperglycemia on admission have high rates of mortality (1). The management of hyperglycemic patients during STEMI is unclear. We evaluate whether the thrombus aspiration (TA) before primary percutaneous coronary intervention (PCI) may improve STEMI outcomes in hyperglycemic patients (2).

Research Design and Methods. Consecutive 990 hyperglycemic patients with first STEMI undergoing quantitative coronary angiography were studied. Patients were categorized in two groups, either treated by thrombus aspiration v/s patients treated without thrombus aspiration. After discharge from the hospital, all patients will be managed and followed quarterly for 12 months month after event, as outpatients, to perform clinical evaluation, routine analyses and cardiovascular evaluation. The cardiovascular endpoint collected in both cohorts will include cardiac mortality, all-cause mortality and hospitalization for coronary disease and heart failure.

Conclusions. We will attend improved outcomes in hyperglycemic patients treated by the TA before PCI, as compared to hyperglycemic patients treated only by PCI.

Gedetailleerde beschrijving

The data analyzed in this study will be obtained from hyperglycemic STEMI patients who underwent primary PCI at the Department of Cardiology of the Cardarelli Hospital in Naples Italy between June 1, 2016, and December 1, 2017. This will be a prospective study to compare two therapeutic strategies: PCI plus thrombus aspiration (TA) versus PCI alone in patients with STEMI and hyperglycemia. According to the recent statement by the American Heart Association, hyperglycemia will be defined as an admission plasma glucose level of >140 mg/dl. Inclusion criteria will include: age of 18 years or greater, presentation to the cardiac catheterization laboratory for PCI in the setting of first STEMI, admission plasma glucose level of >140 mg/dl. All STEMI patients will be referred to the cardiac catheterization laboratory within 12 h of presentation. Patients with left ventricular ejection fraction less than 25%, with previous myocardial infarction or previous PCI or/and coronary by-pass grafting, or had received fibrinolytic therapy will be excluded from the study. The following patients will be referred for urgent invasive diagnostics with the intention of performing PCI: symptom duration of 12 hours or less and ST-segment elevation of 0.1 mV or greater in at least 2 contiguous leads (≥0.2 mV in V1-V3) or presumed new-onset left bundle-branch block. The investigation will be conformed with the principles outlined in the Declaration of Helsinki for use of human tissue or subjects. The Institutional Review Board will approve the protocol.

Outcomes The primary outcome of the THAITI study will be all-cause mortality, cardiovascular deaths, recurrent myocardial infarction, cardiogenic shock, and class IV heart failure within 360 days. Other outcomes will include target vessel revascularisation, stent thrombosis, stroke, and transient ischaemic attack within 360 days.

Studie Bevolking

We will analyze the consecutive patients presenting with acute myocardial infarction and ST segment elevation (STEMI) admitted to the Department of Cardiology of the Cardarelli Hospital in Naples, Italy. Inclusion criteria will include: age of 18 years or greater, presentation to the cardiac catheterization laboratory for PCI in the setting of first STEMI, admission plasma glucose level ( >140 mg/dl in hyperglycemic Group). All STEMI patients will be referred to the cardiac catheterization laboratory within 12 h of presentation. Patients with left ventricular ejection fraction less than 25%, with previous myocardial infarction or previous PCI or/and coronary by-pass grafting will be excluded.

Cohorten en interventies

Groep / Cohort
Interventie / Behandeling
STEMI TA hyperglycemic subjects
STEMI hyperglycemic patients, percutaneous coronary intervention with TA
Percutaneous coronary intervention. Procedures include: Implantation of stents The thrombus aspiration (TA) will be started before crossing the coronary atherosclerosis lesion. A minimum of two syringes (40 mL) of aspirate will be recommended. The guide catheter will be engaged with the coronary ostia when removing the thrombectomy catheter. The guide catheter will be aspirated after thrombectomy to avoid embolisation of air or thrombus. PCI procedure will be done without thrombectomy as per the investigator. Direct stenting will not be mandated in either treatment group. Bailout thrombectomy will be allowed after a failure of the initial PCI alone strategy. The decision about bailout thrombectomy will be made by the interventional cardiologist performing the initial PCI.

Maatregel Beschrijving
Tijdsspanne

Tijdsspanne: 12 months
death caused by loss of heart function such as sudden cardiac arrest or heart attack (myocardial infarction). ECG and cardiac damage markers
12 months
recurrent myocardial infarction
Tijdsspanne: 12 months
Myocardial infarction when there is a blockage in one or more of the arteries to the heart, preventing the heart from receiving enough oxygen-rich blood. If the oxygen in the blood cannot reach the heart muscle, the heart becomes damaged. ECG and cardiac damage markers
12 months
heart failure.
Tijdsspanne: 12 months
Heart failure develops when the heart, via an abnormality of cardiac function (detectable or not), fails to pump blood at a rate commensurate with the requirements of the metabolizing tissues or is able to do so only with an elevated diastolic filling pressure. ECG and echocardiography
12 months
acute coronary syndrome
Tijdsspanne: 12 months
non-ST-elevation acute coronary syndromes (ACSs) and unstable angina. ECG and cardiac damage markers

Target vessel revascularisation
Tijdsspanne: 12 months
Target lesion revascularization was defined as either repeat percutaneous or surgical revascularization for a lesion anywhere within the stent or the 5-mm borders proximal or distal to the stent. Target lesion revascularization was considered to be ischemia-driven if the target lesion diameter stenosis was ≥50% by quantitative analysis with either electrocardiographic changes at rest or a positive functional study in the distribution of the target lesion, or ≥70% with recurrent symptoms only.
