Drug-Eluting Stent Alternatives

Stents are expandable tubes that are used to treat patients with damaged or narrowed arteries.

What are Drug-Eluting Stents?

Drug-eluting stents are small scaffolds made of wire that are inserted into the narrowed coronary arteries of patients with atherosclerosis. The stent helps to hold the artery open and also releases a drug that prevents any further blockage or obstruction occurring in the artery. The stent placement is carried out in a procedure called coronary angioplasty.

Diastolic Dysfunction Treatment

Diastolic dysfunction may take many months or even years to cause symptoms and the slow disease progression means many individuals tolerate the illness without requiring any specific treatment.

Diastolic Dysfunction Diagnosis

The diagnosis and treatment of isolated diastolic failure is often a challenge, since the symptoms are so similar to systolic heart failure.

Diastolic Dysfunction Causes

Diastolic dysfunction is a heart condition that affects the organ’s capacity to fill with an adequate amount of blood during diastole. Diastole is the phase of the cardiac cycle when the heart relaxes following contraction or systole.

Diastolic Dysfunction Pathophysiology

Diastolic dysfunction refers to a mechanical failure of the heart’s chambers to fill properly with blood during the diastole phase of the cardiac cycle. This is caused by inadequate relaxation of the ventricles during diastole.

What is Diastolic Dysfunction?

There are two parts to the pumping action of the heart. The first part is called diastole, when blood collects in the lower heart chambers (right and left ventricles) as it is pushed through the tricuspid and mitral valves.

Arteriosclerosis Types

The types and definitions of arteriosclerosis were described in January of 1954 in the American Journal of Clinical Pathology by S. M. Rabson titled, “Arteriosclerosis: Definitions”. He said that atherosclerosis is defined as arteriosclerosis with atheromatosis.

What is Arteriosclerosis?

Arteriosclerosis is defined as stiffening or hardening or the arterial walls. Arteries are blood vessels that carry healthy, oxygen and nutrient rich blood to the various peripheral organs of the body. As the arterial walls harden, the heart has to pump harder and against a greater resistance to enable that the arterial blood reaches all the peripheral organs.

Carotid Artery Stenosis Treatment

Carotid artery stenosis refers to a narrowing of the arteries that carry blood to the brain from the heart. Also called carotid artery disease, the condition reduces the supply of blood to the brain, which is a major risk factor for stroke or a transient ischemic attack (TIA or mini-stroke).

Carotid Artery Stenosis Diagnosis

arotid artery stenosis refers to a narrowing of the carotid arteries, the major arteries in the neck that supply the brain with blood from the heart.

What is Carotid Artery Stenosis?

Carotid artery stenosis refers to a narrowing of the carotid arteries, which are the major arteries in the neck that supply the brain with blood from the heart.

Cardiac Arrest Ethical Issues

There are several legal and ethical issues surrounding the management of cardiac arrest patients, particularly in the case of an emergency setting that lies outside of the hospital setting. The responsibilities of first responders and initial caregivers are relatively clear but the ethical issues surrounding resuscitation in general are less clear and vary depending on local culture and the law.

Cardiac Arrest Prevention

Cardiac arrest prevention is important and should be attempted by all individuals who are at risk of having cardiac arrest. Recommendations for cardiac arrest prevention are laid out in the European Resuscitation Council Guidelines 2010.

Cardiac Arrest Prognosis

Every year, around 450,000 Americans suffer a cardiac arrest. Of these, nearly 80% occur outside of the hospital setting, usually while the person is at home or at work. The death rate for these out-of-hospital cardiac arrests is at least 90% and of those who do survive, over half have permanent brain damage to some degree.

Cardiac Arrest Treatment

>A cardiac arrest is a sudden failure of the heart to pump blood around the circulatory system to the vital organs. This is a serious medical emergency. For every minute that a person is in cardiac arrest before a defibrillator is available, the chances of survival are reduced by about 10%.
