Intensive Lipid-Lowering Therapy guided by a cloud-based Software System (CLIMEDO GmbH) improves (European Society of Cardiolofgy/European Atherosclerosis Society) ESC/EAS-guideline recommended LDL-cholesterol target attainment and adherence in patients with ST-Elevation Myocardial (STEMI) and Non-ST-Elevation Myocardial Infarctions (NSTEMI).
Patients who suffered from acute coronary syndrome (ACS) are usually treated with a long-term dual antiplatelet therapy (DAPT) to reduce stent thrombosis and recurrent ischemic event. Nonetheless, recent important data have demonstrated the efficacy of a short term DAPT and an early single antiplatelet therapy in high bleeding and ischemic risk patients. The bleeding risk is associated with a significant mortality. This risk is especially high in patients treated with potent P2Y12 inhibitors like ticagrelor or prasugrel after an ACS. As a result of the abounding data regarding the safety of an early single antiplatelet therapy with high potency antiplatelet therapy (ticagrelor or prasugrel), it is likely that such strategy will soon be implemented in the guidelines. The benefits of these high-potency P2Y12 inhibitors over clopidogrel mostly occur in patients with genetic polymorphisms of CYP2Y12 associated with a loss of function in clopidogrel metabolism. Furthermore, the anti-ischemic benefit of potent P2Y12 inhibitors over clopidogrel occurs early, while excess bleeding events often arise during chronic treatment. Our hypothesis is that a systematic and rapid genetic screening of CYP2C90 *2 or *17 polymorphism to guide an early single therapy with low potency antiplatelet (aspirin or clopidogrel) could lead to less bleeding events with a consistent efficacy towards cardiac events compared with high potency antiplatelet therapies (prasugrel or ticagrelor) in high bleeding risk patients treated for ACS.
The purpose of this study was to evaluate the efficacy and safety of ketotifen (MC stabilizer) on the basis of standard treatment after primary PCI in STEMI patients. The ketotifen group and the control group were the ketotifen group and the control group. The control group continued to receive STEMI standard treatment. The ketotifen group received ketotifen for 3 months on the basis of standard treatment within 24 hours after primary PCI, and was followed up for 1 year. Infarct size, as well as differences in echocardiography, markers of two-dimensional speckle tracking, inflammatory factors and MC markers, and major adverse cardiovascular events.
Coronary heart disease (CHD) is the leading cause of mortality worldwide. Every year, millions of people suffer its most adverse manifestation, an acute myocardial infraction (AMI). The majority of these patients present at least one of the standard modifiable risk factors (SMuRFs). These include smoking, hypertension, dyslipidemia, and diabetes mellitus (DM). However, emerging scientific evidence recognizes a clinically significant proportion of patients presenting with life-threatening AMI without any SMuRF (SMuRF-less patients). This proportion of patients with ACS without SMuRF appears to be increasing during the last two decades and has recently been reported as high as 20% (of total AMIs). To date, there are no scientific data capable of highlighting specific risk factors-biomarkers responsible for the development of AMIs SMuRF-less patients. Concurrently, metabolomics is rapidly evolving as a novel technique of studying small molecule substrates, intermediates and products of cell metabolism. This technique could be utilized to flag patients with higher risk for increased atherosclerotic burden, and subsequent future adverse clinical events. Besides the already established biomarkers, several metabolomic indicators, such as ceramides (C16, C18 και C24), acylcarnitines, apolipoproteins (ApoΒ and ApoA1) and adiponectin, have been separately shown to increase the risk for coronary artery disease development and progression. Therefore, the two groups of patients (with SMuRFs vs SMuRF-less) will be compared regarding their metabolic fingerprints -specifically the aforementioned novel metabolomic biomarkers- and possible predictive factors leading to SMuRF-less AMI will be evaluated. On the basis of the above, the aim is to prospectively analyze a cohort of well-characterized patients with AMI. The rationale of the study is to investigate potential correlations between metabolic profile of patients and SMuRF-less AMI. This could lead to the development of predictive risk stratification algorithms for patients without SMuRFs and coronary artery disease.
Acute myocardial infarction (AMI), triggered by myocardial ischemia and reperfusion injury, is a disease with high morbidity and mortality, and there is a tendency for its incidence to increase at younger ages. One of the most worrisome complications of primary percutaneous surgery is contrast-induced nephropathy, which is associated with increased mortality and morbidity in myocardial infarction after coronary interventions. In many studies, inflammatory markers, which are thought to give an idea about the development of contrast-related nephropathy, have been examined. The transcription factor nuclear factor erythroid 2-related factor 2 (Nrf2) is a master regulator of cytoprotective protein expression driven by antioxidant response agents (AREs) and plays a decisive role in the regulation of oxidative defense and redox homeostasis in cells. There are studies showing the role of Nrf2 in the pathogenesis of kidney damage in some studies. Studies on the effect of Nrf2 level on contrast media nephropathy in patients with contrast media nephropathy (CIN) are limited in the literature. This study also aimed to form a basis for the literature, which is a small number of studies, in later studies.
The incidence of cardiovascular disease is still high in China under the condition of non-standard treatment of Western medicine. Acute coronary plaque rupture and thrombosis is an extreme manifestation of instability of "vulnerable plaque", which is the result of the joint action of multiple factors. The intervention of unstable plaque reversal from multiple factors is inherently reasonable. Compared with the treatment of thrombosis and unstable plaque in western medicine, quick acting Jiuxin Pill can not only calm and relieve pain for pain and other symptoms, but also regulate immune inflammation and metabolic disorder, improve microcirculation and anti myocardial ischemia. In order to evaluate the efficacy, safety and modern scientific basis of Suxiao Jiuxin Pill in acute myocardial infarction (AMI), the investigators designed this study.
Angiographic no-reflow during primary PCI procedures occurs at relatively high rate (25%) and is associated with worsening of long term morbidity and mortality. The exact mechanism of no-reflow is not fully understood, yet it is believed to be multifactorial including microvascular plugging with activated platelets and thrombotic debris in addition to the microvascular dysfunction from the ischaemia-reperfusion injury. Despite a theoretical advantage of glycoprotein IIb/IIIa inhibitors (GPi) (like; Tirofiban) to suppress the intense platelets' activation/reaction; their use did not lead to a significant net benefit, because it was opposed by increased risk of bleeding. However, the bleeding that plagued GPi use was predominantly related to vascular access in the era femoral approach was the default. Moreover, there are some recent data suggesting that small intracoronary bolus of GPi was non-inferior to intravenous bolus-infusion dose with less bleeding events. This study plans to assess upfront premedication with small doses of GPi + Nitroglycerin ± Verapamil, with staged restoration of flow (repeated balloon inflation) to reduce angiographic no-reflow and CMR assessed microvascular occlusion (MVO).
Acute Myocardial Infarction (AMI) is a major disease that endangers people's health China. At present, clinical emphasis is given to "treatment" rather than "prevention", and a large number of AMI patients are hospitalized repeatedly without systematic and standardized health management after acute stage, falling into a vicious circle of "treatment without recovery". Nurse-led case management based on multidisciplinary collaboration is a new mode of disease management. In 1994, the United States took the lead in applying case management to the acute and chronic care system, providing comprehensive care services and promoting comprehensive recovery through multidisciplinary collaboration led by case managers. At present, the case management model of cardiovascular disease in Europe and the United States has been mature, but it is still in the exploratory stage in China. Through the establishment and application of nurse-led AMI case management program based on multidisciplinary collaboration, this study wants to establish a novel, standardized, and easy to popularize AMI whole-course prevention and control mode, providing theoretical and research basis for AMI disease management.
