Different stent graft types to repair thoracic aortic aneurysms | Cochrane

An aneurysm is a localised widening of an artery. The thoracic aorta is the largest artery in the body, delivering blood from the heart to the arms and head. If an aneurysm occurs in the thoracic aorta it can expand and may rupture, resulting in death. Open surgery can treat these aneurysms, which involves opening the chest and placing an artificial graft over the widening. A new alternative treatment involves an artificial stent graft, delivered through an arterial blood vessel in the groin, fixed over the widening. This technique is called endovascular repair. There are many different types of stent grafts available. They differ in how they are inserted into/access the blood vessel, how they attach to the walls of the artery and the design and materials they are made from.

Different stent grafts for repair of abdominal aortic aneurysms | Cochrane

An aneurysm is a localised widening of an artery. The abdominal aorta is the largest artery in the body, delivering blood from the heart to the organs in the abdomen and the legs. If an aneurysm occurs in the abdominal aorta it can expand and may rupture, resulting in death. Open surgery can treat these aneurysms; this involves opening the abdomen and placing an artificial graft over the widening. A new alternative treatment involves an artifical stent graft, delivered through an arterial blood vessel in the groin, fixed over the widening. This technique is called endovascular repair.

Calcium channel blockers for pulmonary arterial hypertension | Cochrane

The blood pressure in the arteries of the lungs is normally much lower than the blood pressure in the rest of the body. Pulmonary hypertension occurs when the pulmonary arterial pressure gradually rises which causes damage to the heart, and can finally lead to heart failure and death. Calcium channel blockers are drugs which can relax the pulmonary arteries and decrease resistance and pressure of these vessels; this may benefit patients with pulmonary hypertension.

Pentoxifylline for intermittent claudication | Cochrane

Atherosclerosis, or hardening of the arteries, results in narrowing and blockage of the arteries and can reduce the blood supply to the legs, causing peripheral arterial disease. Intermittent claudication (IC) is a cramp-like pain felt in the leg muscles that is brought on by walking and is relieved by standing still or resting. Pentoxifylline is a drug that is used to relieve IC while improving people's walking capacity. It decreases blood viscosity and improves red blood cell flexibility, promoting microcirculatory blood flow and increasing oxygen in the tissues. This review looked at all available evidence from randomised controlled trials on the efficiency of pentoxifylline for treatment of IC.

Drugs to dissolve pulmonary embolism (blood clot in the lungs) | Cochrane

A pulmonary embolism is a potentially fatal blood clot that lodges in the main artery of the lungs, straining the right side of the heart and affecting blood circulation. Patients are also at risk of new embolisms forming (recurrence). In the case of a massive pulmonary embolism, treatment to restore blood flow is urgently required. Heparin thins the blood, but newer drugs that actively break up the clots (thrombolytics) may act more quickly and be more effective. These newer drugs include streptokinase, urokinase and recombinant tissue-type plasminogen activator. The major complication of this treatment is bleeding.

Stem cell treatment following a heart attack | Cochrane

Background: Currently the standard treatment for people suffering a heart attack (due to a blockage in the artery supplying blood to the heart) is direct opening of the artery with a tiny balloon in a procedure called primary angioplasty and introduction of a small tube (called a stent) into the artery to keep it open. The use of primary angioplasty and stents to reopen the blocked artery can lead to a 35% reduction in the mortality (death rate) associated with this condition. In recent years, bone marrow stem/progenitor cells have been investigated as a potential treatment. They may prevent the damage to the heart muscle caused by a heart attack, when used in addition to the treatment offered by primary angioplasty and standard medical therapy.

Hemostasis is an essential step in wound management. Most commonly, bleeding is caused by lacerated subdermal plexus and superficial veins which can be controlled with pressure alone. When lacerations are especially deep, an artery may also be affected. In these situations, special maneuvers are often necessary to obtain adequate hemostasis.

Deferring Stent After Infarct-Artery Opening May Limit MI Size

Calling this a "very clever" strategy, one expert noted it did suggest superiority over immediate stenting. "I don't think it's the final answer, but I congratulate them on the concept."

Emergency Medicine Literature of Note: The Unintended Harms of “Quality”

I'm always skeptical when FP rates for STEMI systems are less than 10-15%, probably a lot of vulnerable myocardium left out there...but that hinges on their definition of "false positive", something not exactly perfect in most systems.I'm left wondering how PE, ICH, and sepsis made it into STEMI activations given that they don't typically present with ST-e localized to a wall/artery (perhaps they're activating on undifferentiated subendocardial ischemia, popularized by ST-e in aVR w/ widespread ST-d).Aortic dissections I'm familiar with as a "mimic", as they can manifest with localized ST-e and instead must be differentiated by non-ECG findings. Makes sense that speeding up cuts out time for that differentiation.It does go to show the inevitable, that when you pick a metric to optimize against your system will work to that metric whether it is right, wrong, or indifferent and you'll enjoy the consequences of that optimization. (I think the authors should be commended for studying the effect on their patients after making a system level change)
