The source of adipocytes in arrhythmogenic cardiomyopathy
Arrhythmogenic Cardiomyopathy (ACM) is a genetic disorder characterized by progressive fibro-fatty substitution of the heart, arrhythmias and sudden death. It affects mainly young people and athletes. The clinical manifestations, often devious in early phases, are variable. The
Arrestin-enolase protein complex as a new auto antigen in heart disease
Over the past two decades, evidence of a pathogenic relevance of autoimmunity in human heart disease has increased significantly. A central role for autoimmunity in a significant proportion of dilated cardiomyopathy (DCM) patients is supported by the
A novel miniaturized Reveal LINQ insertable cardiac monitoring system, the guarding angel of your heartbeat
An arrhythmia is a problem with the rate or rhythm of the heartbeat. It means that your heart beats too quickly, too slowly, or with an irregular rhythm pattern. When the heart beats faster than normal, it
CKD affects mortality in TAVI patients
Aortic stenosis (AS) is the most frequent type of valvular heart disease in Europe and North America. It primarily presents as calcific AS in old people (2–7% of the population > 65 years). Calcific AS is a
Palliative treatment of superior vena cava syndrome with use of stent
Superior vena cava (SVC) syndrome is a clinical diagnosis that is caused by compromised venous blood return from the head and upper extremities due to compression and obstruction of the SVC. Respiratory distress, dysphagia, swelling of the
Structure function relationship of gap junctions, the structure that permits heart cells to contract synchronously
The heart is constituted by cells that contract synchronously thereby allowing pumping of the blood to all the organs around the body of animals that possess a circulatory system. The trigger that initiates this contraction is an
Post electric shock cardiac arrest, does it differ?
Sudden cardiac arrest (CA) is a medical emergency that immediately causes circulatory failure with loss of consciousness; absence of breathing; low blood pressure with no pulses; and no heart sounds. The most common causes of CA are electrical
Finding new drug targets to prevent heart attacks and strokes
心attacks and strokes are responsible for more deaths than any other disease in the world. The underlying cause of most heart attacks and strokes is a disease of the blood vessels called atherosclerosis. Atherosclerosis involves accumulation
Replacing diseased arteries: are we close enough?
Medical device technology has advanced to an extent that artificial heart, kidney, arteries, and prosthetic limbs are available as commercial market products. It is now a matter of choice for the patient and the surgeon to choose
High prevalence of undertreated cardiovascular disease in patients diagnosed with cancer
心disease and cancer are the most common causes of death in the United States. They often have the same risk factors (for example, smoking, advancing age, obesity). Heart disease can worsen outcomes after cancer therapy and
Ultrasounds for heart infections can be reduced by following simple rules
Staphylococcus aureus bacteria often cause severe bloodstream infections, called Staph aureus bacteremia (SAB). Once Staph aureus enters the bloodstream it can spread to the heart and cause an infection of the heart valves called infective endocarditis (IE).
A formula for better asthma, cold and heart medications
Imagine that you had found a way to drop the dose of your asthma medication ten-fold, increase its duration of activity from a couple of hours to all day, and still get the same relief as before.
What role do medications play in changes in sexual activity after a heart problem?
心disease affects millions of people worldwide. While advances in medical treatment have allowed many with heart disease to live longer, healthier lives, changes in quality of life often occur. This is particularly true for sexual activity,
Two essential cardiac disorders improvement in patients with hypertrophic cardiomyopathy
Sudden cardiac death and heart failure are the most serious complications of hypertrophic cardiomyopathy ( HCM ). To prevent these serious complications, 2 essential cardiac disorders in patients with HCM must be corrected. These are left ventricular (LV)
Should you be taking a statin drug?
Millions of patients are currently treated with cholesterol-lowering statin drugs that are prescribed to prolong life and prevent heart attacks. For patients who have never had a heart attack or stroke (primary prevention), statin therapy is typically
Tricking the body into building new heart valves and blood vessels
当心脏瓣膜或小血管失败,苏尔gically implanting a replacement can be a life-saving operation. Right now, replacement blood vessels are harvested from the patient’s leg or chest, which is an additional invasive procedure. Heart
Minimizing injuries from acute myocardial infarction
Reperfusion therapy is currently the mainstay treatment of acute myocardial infarction, as it salvages myocardial cells from ischemic cell death. However, abrupt restoration of coronary blood flow induces another type of cell death called “lethal reperfusion injury,”
Death and stroke risks after surgical aortic valve replacement: A real world perspective
With a rapidly rising proportion of aging population, aortic stenosis (AS) represents one of the most common valvular heart diseases affecting adults in the US and accounts for at least 92,000 aortic valve replacements (AVR) annually in
Fainting – a hearty matter
Fainting and feeling like fainting (syncope and presyncope) is a very common symptom, which most people ignore. And in most of the cases, especially in sporadic occurrences with obvious reasons (tiredness, alcohol intake, orthostasis etc), that’s a
Survivals in pediatric cardiac tamponade caused by central venous catheters
Pediatric central venous catheter (CVC) placement is used for fluid or drug administration and is useful for hemodynamic (the fluid dynamics of flow) management in cardiac surgery but associated with complications such as rare but serious cardiac
