Are there benefits of cardiac catheterization for stable coronary artery disease?

One of the main causes of chest pain is a blockage of blood flow down the coronary arteries, the blood vessels that deliver oxygenated blood to our heart muscle to allow it to beat. Depending on how fast the blockage forms, it is labeled as either a stable or unstable blockage. Unstable blockages occur quickly when an atherosclerotic plaque ruptures within the coronary artery and a clot forms on top of it. The clot, along with the plaque, can obstruct blood flow, deprive heart muscle of oxygen, and lead to a heart attack. This is called an acute coronary syndrome, and it frequently requires a minimally invasive procedure called a cardiac catheterization to diagnose the blockage and then provide options to treat it. When the buildup of plaque in the coronary arteries occurs gradually, most patients have little to no symptoms. As the blockage expands over time, patients can experience chest pain with activity that usually goes away with rest. When a blockage causes this predictable pattern of chest pain, it is called stable coronary artery disease (CAD). A cardiac catheterization may or may not be needed to manage stable CAD. Stress tests A stress test can be used to determine the likelihood of having a coronary artery blockage. The main goal of the test is to see how your heart works during physical activity. Because exercise makes your heart pump harder and faster, an exercise stress test can reveal problems with blood flow within the coronary arteries. Certain types of stres...

AbstractThe use of cocaine constitutes a major health problem. Cocaine use is associated with acute and chronic complications that might involve any system, the most common being the cardiovascular system. The precise incidence of cocaine-induced cardiomyopathy remains mysterious and probably underreported. Cocaine use should be considered in young patients presenting with chest pain or heart failure without other underlying risk factors. Cocaine-related cardiovascular complications can be acute or chronic and include ischemic and non-ischemic events. Frequent cocaine users have a seven-fold higher risk of myocardial infar...

CONCLUSION: On the basis of a broadly based research and participatory development process, a set of indicators has been developed that enables comprehensive evaluation of the regional quality of care of cross-indication, integrated care models focusing on common diseases. In order to be able to increasingly evaluate aspects of care coordination and patient orientation, health promotion as well as nursing, palliative and emergency care in the future, it would be helpful if routine data were collected or made accessible in these areas as well.

NEW BRUNSWICK, NJ, May 27, 2020 — The Janssen Pharmaceutical Companies of Johnson &Johnson today announced that the U.S. Food and Drug Administration (FDA) has granted approval for a new pediatric formulation of SIRTURO® (bedaquiline). SIRTURO® is now indicated for use as part of combination therapy in the treatment of adult and pediatric patients (5 years and older and weighing at least 15 kg) with pulmonary multidrug-resistant tuberculosis (MDR‑TB). In the U.S., the medicine should be reserved for use when an effective treatment regimen cannot otherwise be provided. This indication received accelera...

Rationale: Patent foramen ovale (PFO) is not considered to be the main cause of stroke and is classified as the infarction of undetermined cause. The relationship between PFO and cerebral embolism is still unclear and cerebral embolism accompanied with coronary artery embolization in PFO patient is rare. In this case, we reported a patient with PFO suffered acute cerebral and myocardial infarction simultaneously, and analyzed the source of emboli and potential pathogenesis. Patient concerns: A 53-year-old female presented with chief complaints of intermittent palpitations and chest tightness for 6 years, aggravated fo...

AbstractAcute coronary syndrome is a precipitant of acute heart failure in a substantial proportion of cases, and the presence of both conditions is associated with a higher risk of short ‐term mortality compared to acute coronary syndrome alone. The diagnosis of acute coronary syndrome in the setting of acute heart failure can be challenging. Patients may present with atypical or absent chest pain, electrocardiograms can be confounded by pre‐existing abnormalities, and cardiac biomarkers are frequently elevated in patients with chronic or acute heart failure, independently of acute coronary syndrome. It is important t...

In conclusion, our study demonstrated that Nrf2 deficiency promoted the increasing trend of autophagy during aging in skeletal muscle. Nrf2 deficiency and increasing age may cause excessive autophagy in skeletal muscle, which can be a potential mechanism for the development of sarcopenia.

Abstract Prostanoids are a group of bioactive lipids that are synthesized de novo from membrane phospholipid-released arachidonic acid and have diverse functions in normal physiology and disease. NSAIDs, which are among the most commonly used medications, ameliorate pain, fever, and inflammation by inhibiting COX (cyclooxygenase), which is the rate-limiting enzyme in the biosynthetic cascade of prostanoids. The use of NSAIDs selective for COX-2 inhibition increases the risk of a thrombotic event (eg, myocardial infarction and stroke). All NSAIDs are associated with an increased risk of heart failure. Substantial v...

Abstract Takotsubo syndrome (TTS), also known as stress cardiomyopathy, is a type of acute heart failure syndrome triggered by intense psychological or physiological stress. TTS typically manifests as acute chest pain, dyspnea or syncope that mimics an acute myocardial infarction but does not involve coronary artery obstruction. The current understanding of the pathogenesis of TTS suggests that sympathetic nervous system (SNS) activation plays a central role. Specifically, stress can activate the SNS and lead to the over-release of catecholamine, which have toxic effects on myocardial tissue when present at excess...
