Summary: This prospective study aims to compare functional abnormalities detected using myocardial perfusion SPECT imaging (MPI SPECT) with the extent and severity of anatomical findings on coronary computed tomography angiography (coronary CTA). Additionally, the investigators aim to enhance the diagnostic value of MPI SPECT by quantifying myocardial blood flow and utilizing myocardial flow reserve calcul...

Summary: This study aimed to investigate the effect of low-dose (100 mg) asprin on the prevention of gastric cancer in the early gastric cancer patients with negative H. pylori status who underwent endoscopic submucosal dissection.

Summary: The aim of this study is to document an optimized pharmacologic treatment for patients with Takotsubo Syndrome. There is currently no published documentation in a large number of patients. The study is a Randomized Registry Clinical Trial and in total 1000 patients registered in SWEDEHEART will be included.

Summary: A fifth of ischemic stroke or transient ischemic attack (TIA) patients will have recurrent events within the first 3 months \[Refs 1-3\] despite aggressive medical therapy with antiplatelets and risk factor control. Clopidogrel is one of the mainstays of antiplatelet secondary prevention therapy in patients with ischemic stroke. CYP2C19 loss of function (LOF) mutations impair the effectiveness of ...

Summary: This study tries to identify the safe and effective treatment option for IgA nephropathy in children. Investigators will perform prospective registration study among 25 pediatric nephrology medical centers in China.

Summary: With stress echo (SE) 2020 study, a new standard of practice in stress imaging was developed and disseminated: the ABCDE protocol for functional testing within and beyond CAD. ABCDE protocol was the fruit of SE 2020, and is the seed of SE 2030, which is articulated in 12 projects: 1-SE in coronary artery disease (SECAD); 2- SE in diastolic heart failure (SEDIA); 3-SE in hypertrophic cardiomyopathy...
