CV+ Blood What happens in MI- A heart attack (myocardial infarction) is usually caused by a blood clot, which stops the blood flowing to a part of your heart muscle. You should call for an ambulance immediately if you develop severe chest pain. Treatment with a clot-busting medicine or an emergency procedure to restore the blood flow through the blocked blood vessel are usually done as soon as possible. This is to prevent or minimise any damage to your heart muscle. Other treatments help to ease

Heart failure (HF) is one of the most common manifestations of heart disease. In the US, the lifetime risk of developing HF at age 40 is one in five for both men and women, and continues at this level through the age of 80, despite the reduction in life expectancy.{Roger, 2012 #1789} Chronic HF in particular has increased in prevalence, even as control of other common cardiovascular syndromes, such as myocardial infarction (MI), has improved in recent years.{McCullough, 2002 #1851;Roger, 2012 #1789}

legs are results from the electrolyte imbalances the patient is enduring. “Oh, my dear, you look just like an angel” The statement made by the patient indicates a noncardiac adverse effect to the patient’s use of digoxin for atrial fibrillation. Atrial fibrillation is due to the electrolyte disturbances, decrease in all phases, and the deprivation of oxygen in the body, or hypoxia, and elevated preload. (McCance 1196). Digoxin uses a positive inotropic action on the heart by increasing the force

If the QRS is present and the pattern is sever, it is a sign of atrial flutter. Also, a sine wave shows ventricular flutter, and the absence of P waves with wide QRS complexes is ventricular tachycardia. Therefore, it is very important to consider the rate and rhythm of the heart beat in ECG recording. Moreover, axis

How does an understanding of the mechanisms of the heart help you in treatment of your patient regardless of the illness? The heart is a muscular pump that keeps blood flowing through the vessels, sending oxygen and nutrients to all parts of the body, and carrying away unwanted carbon dioxide and waste products. Having an understanding of its functions and mechanism is essential for the care of the patient. Let’s take for example a patient with Left-sided Heart failure. Because blood is not pump

infarction in the past three decades, acute myocardial infarction continues to be a major health problem. About 50% of death from acute myocardial infarction occur within 1hr of the event and are attributable to arrhythmias most often ventricular fibrillation. Ischaemic injury can produce conduction blocks at any level of the atrioventricular or Intraventricular conduction systems. Such conduction block can occur in the atrioventricular node producing various grades of AV block. Conduction block can

Accumulation of zoledronic acid over time can cause significant renal toxicity and damage. Additional short-term adverse effects include fever, upper GI upset and musculoskeletal pain. Long-term adverse effects include jaw osteonecrosis, atrial fibrillation and suppression of bone turnover. In the case patient, additional risks include atypical femoral fractures, impaired growth and hypocalcaemia. In particular, hypocalcaemia can manifest from a few days to several months after initiation
