Instantaneous Wave-Free Ratio and Fractional Flow Reserve for the Assessment of Non Culprit Lesions...
ST Segment Elevation Myocardial InfarctionFunctional assessment of non-culprit lesions during percutaneous coronary intervention (PCI) in patients with acute coronary syndrome could improve risk stratification and shorten the duration of hospital stay by decreasing the need for additional non-invasive stress testing to detect residual myocardial ischemia. The investigators aimed to assess the reliability of the instantaneous wave-free ratio (iFR) and fractional flow reserve (FFR) measurements in non-culprit coronary lesions during the acute and subacute phase of ST-segment elevation myocardial infarction (STEMI).
The Contemporary Role of Beta Blockers in Patients With Acute Myocardial Infarction
Acute Coronary SyndromeThe use of beta blockers after acute myocardial infarction is a core component of drug therapy, but evidence is primarily derived from patients who did not receive reperfusion therapy and secondary prophylaxis.In contemporary times, the prognostic value of beta blockers in patients with acute myocardial infarction has been questioned, particularly in patients without reduced heart failure/ejection fraction after acute myocardial infarction.
Left Ventricular Free-wall Ruptrue After Acute Myocardial Infarction (LVFR-AMI)
Acute Myocardial InfarctionThe Left Ventricular Free-wall Ruptrue (LVFR) is a serious complication caused high mortality.

Short-term Air Pollution Exposure and In-hospital Outcomes in Patients With Acute Myocardial Infraction...
Air PollutionAcute Myocardial Infarction1 moreThe aim of this study is to investigate whether or not short-term expose to air pollution is associated with in-hospital outcomes, such as mortality and morbidity.
MRI Study of the Structural and Functional Rehabilitation in the Cerebral Infarction Patients With...
Cerebral StrokeDiabetes MellitusDiabetes mellitus (DM) plays an important role in the occurrence of the cerebral infarction (CI). Clinical studies have demonstrated that the CI patients with DM had a poor prognosis compared with those without DM. Previous magnetic resonance imaging (MRI) studies have shown that patients with DM had abnormalities in cerebral vessels, nerves and functions, similar with the findings in mice models. In this study, with multi-modal MRI technologies, investigators tend to observe structural and functional changes of the brain in both DM and non-DM CI patients and assess their neural rehabilitation using clinical scales in the following 6 months. Investigators also expect to find out dynamic changes of brain structure and function, to reveal the weights of factors including brain blood vessels, nerves and function remodeling related with stroke recovery, as well as the potential mechanism in CI patients with DM.
Earlobe Creases Predict Prognosis in Chinese Patients With Acute Myocardial Infarction

Ear/*AbnormalitiesRisk FactorThe purpose of this study is to explore the earlobe crease as a risk factor of acute myocardial infarction (AMI)in the Chinese population, combined with other risk factors, to predict high risk patients with coronary heart disease.
Fractional Flow Reserve Versus Angiography for Guiding Selective Percutaneous Coronary Intervention...
Fractional Flow ReserveST-segment Elevation Myocardial Infarction1 moreTo assess the outcomes of patients with ST-segment elevation myocardial infarction (STEMI) assigned to fractional flow reserve (FFR) and angiography-guided selective percutaneous coronary intervention (PCI).
Finding LCX AMI With Posterior ECG LeadS
Myocardial InfarctionAlong with symptoms of chest pain, the presence of ST segment elevations on ECG is the criterion usually used in practice to identify patients with acute coronary artery occlusion and is essential for the direct and acute referral of patients for primary PCI. However, ECG does not always reflect changes in the posterior wall of the heart, often equivalent to the left circumflex coronary artery's (LCX) supply area, resulting in an underrepresentation of LCX as culprit artery in STEMI populations. There is a general concern that some patients with genuine acute occlusion of LCX may present without ST segment elevation and be denied reperfusion therapy, resulting in larger infarction and worse outcome. The aim of this trial is to implement record of posterior ECG leads (V7, V8 and V9) in addition to the standard 12-lead ECG in the pre-hospital setting and to evaluate the clinical impact of this implementation: In comparison to a control cohort of STEMI patients diagnosed with a pre-hospital standard 12-lead ECG prior study start, the investigators hypothesize that introducing V7-V9 leads as a clinical routine in the pre-hospital setting will identify patients with STEMI involving LCX and with a non-diagnostic standard 12-lead ECG.
