Filter by:The essential arterial hypotension and allostasis registry is a prospective, observational research that has the purpose of demonstrating that essential blood pressure (BP) disorders and the associated comorbidities are a result of the inappropriate allostatic response to daily life stress. This required a functioning brain orchestrating the evaluation of the threat and choosing the response, this is a mind-mediated phenomenon. If the response is excessive it contributes to high BP, if deficient to low BP, and the BP itself will identify the allostatic pattern, which in turn will play an important role in the development of the comorbidities. To do so, consecutive patients of any age and gender that visit a cardiologist's office in Medellin, Colombia, are recruited. Individuals are classified according to their arterial BP and allostasis and follow them in time to see what kind of diseases develops the most (including BP) in the follow up according to the categorization of the characteristic chosen and after adjustment for confounder's variables. In addition, stress events with their date are registered. HYPOTHESIS The causes of the diseases are multifactorial. Physical, biochemical, psychological, social, and cultural dimensions of development dynamically interact to shape the health development process. A person´s health depends on their: 1. Biological and physiologic systems 2. External and internal environment (a) physical, b) internal behavioural and arousal state as registered by the brain. 3. Their interaction. The allostatic mechanisms to the internal and external stressors (allostatic load) involves a network composed by: 1. Functional systems; mediated by: 1. The Autonomic Nervous System 2. The endocrine system 3. The immune system 2. Structural changes: whenever the internal and/or external stressors are long lasting and/or strength enough, they may induce changes in: 1. Epigenetic, endophenotypes, polyphenism. 2. Plasticity 3. The interaction between a) and b). The network response do not affect exclusively the BP, propitiating the development of comorbidities, which may prompt strategies for prevention, recognition and ultimately, treatment. The allostatic model defines health as a state of responsiveness. The concept of psycho-biotype: The allostasis is the result of both: biological (allostasis) and psychological (psychostasis) abilities. It is proposed that both components behave in similar direction and magnitude. Immune disorders may be associated with the development of cancer. High BP population has a higher sympathetic and lower vagal tone, this has been associated with a decrease in the immune´s system function. Resources and energy depletion: Terms like weathering have been used to describe how exposures to different allostatic loads gradually scrape away at the protective coating that keeps people healthy. It is postulated that High BP individuals have more resources and energy.
Recently, two new oral P2Y12 antagonists have been approved for clinical use: prasugrel, a third generation thienopyridine, and ticagrelor, a first in class cyclopentyltriazolopyrimidine (CPTP). These agents have been shown to be associated with more potent platelet inhibitory effects compared with clopidogrel. In addition, both agents have shown to be superior to clopidogrel in preventing recurrent ischemic events in the setting of acute coronary syndromes (ACS). Understanding how to switch patients from prasugrel to ticagrelor is an unmet need of clinical interest. The proposed PD investigation will have a prospective, randomized, parallel design aimed to show that switching patients from prasugrel to ticagrelor provides similar levels of platelet inhibition.
To test the hypothesis that early (within 5-21 days after index event) administration of combined lipid-lowering therapy in extremely high risk population of patients with type 2 diabetes mellitus (T2DM) and hypertriglyceridemia (HTG) who experienced acute coronary syndrome (ACS) will be effective and well tolerated in achievement of contemporary strict requirements for triglyceride (TG) levels as an independent risk factor in the case of HTG with diabetes.
This register will evaluate the use of different antithrombotic therapies, combinations of different drugs routinely used during any stage of hospital admission, with their timing, dosage and mode of administration, in patients with a diagnosis of Acute Coronary Syndrome in the Italian Coronary Care Unit during a study period of three weeks
to evaluate the incidence of delirium in patients with acute coronary syndrome and its correlation with adverse events
In this proof-of-concept study, the investigators will assess the ease and usefulness of a positive psychology program in patients with acute coronary syndrome and less-than-optimal adherence to health behaviors. The investigators believe that positive psychology (a field that studies boosting positive emotions rather than simply reducing negative emotions) will help this cardiac population to be more healthy. The investigators want to determine whether this positive psychology program has the potential to be an adjunctive treatment for cardiac populations.
1. In chest pain patients with suspected acute coronary syndrome, a 2-hr delta Troponin-I as measured by the i-STAT immunoassay reliably identifies and excludes an acute myocardial infarction. 2. In chest pain patients with suspected acute coronary syndrome whose baseline troponin is above the 99th percentile but less than 0.2ng/ml, a 2hr delta Troponin-I as measured by the i-STAT immunoassay accurately discriminates between acute myocardial infarction and non-acute myocardial infarction troponin elevations.
RE-ACT is a national, multi-centre, observational, prospective, longitudinal cohort study which will include patients hospitalized for ACS within 24 hours of symptom onset and who have a final diagnosis of ST-segment elevation myocardial infarction (STEMI) or non-ST-segment elevation myocardial infarction (NSTEMI). This study aims to describe the short-term (at the end of the first month after index event) antithrombotic management patterns in a "real-life" setting for patients hospitalized with an acute coronary syndrome.
Fractional flow reserve (FFR) is a test that can be performed at the time of heart catheterization. It measures the change in pressure across a narrowing in the heart artery during high flow situation, and provides reliable information about the functional severity of the narrowing. FFR measurements accurately predict whether a stent is needed, and is considered an excellent test before placement of stents to treat narrowed heart arteries. However, FFR is not used in every case because of the extra time needed and the associated device costs. Cardiac Services BC (an agency of Provincial Health Services Authority) is sponsoring this study to find out if FFR should be used in most cases (routine), rather than the current selective approach.
The Ladies ACS study will investigate the relation between age at menopause and severity of coronary artery disease in menopausal women with acute coronary syndromes and clinical indication to coronary angiography.
