Medical conditions are bound to increase due to change in lifestyles. One of the life threatening conditions is heart failure. The heart is a muscular structure that pumps blood to all parts of the body. Heart failure results when the heart fails to pump enough blood hence increased overload. The pathophysiology occurs as a result of increased workload on the left ventricle especially in patients with hypertension. This leads to enlargement of the muscles; enlarged muscles lack sufficient oxygen…

Jaida Marks Mrs. Pangaio Honors Anatomy and Physiology 3 September 2015 Shivering when you get cold or sweating when you are hot, are both very common examples of your body trying to maintain homeostasis. Homeostasis is the ability of your body to maintain stable internal conditions when faced with environmental changes. Sometimes there can be a stimulus in the environment that will cause changes to an organism's stable internal conditions. This results in the organism responding using…

diagnosis: Diagnosis is usually made from patient history and find other causes of heart failure. (The signs and symptoms for heart failure dyspnea, fluid retention, peripheral edema, nausea.) The most helpful tools of the diagnosis is echocardiogram. The chest x-ray identify the heart enlargement. Character’s : • Heart failure symptoms, including unexplained right heart failure • Arrhythmias • Conduction abnormalities • Thromboembolic events • angina pectoris managements : Heart-Healthy…

could increase the sympathetic activation of the heart (153). It can increase the heart rate and cause orthostatic hypotension (160). The TCA induced orthostatic hypotension can be further aggravated on MI patients who are taking beta blockers and angiotensin converting enzyme inhibitors (161). They may also alter the conduction system and be more vulnerable to ventricular arrhythmia (162). TCAs are advised to be avoided in ischaemic heart disease and ventricular…

result in reduction in preload and afterload. These drugs increase vasodilatory effects causing reduction in blood pressure. Risk factors include diabetes, more than 70 years of age and co-administration with other agents that affect the renin angiotensin aldosterone system (RAAS) such as ACE inhibitors and beta blockers (O’Donovan, 2014). Beta blocking agents is another example of anti-hypertensive drugs. The immediate effect is to reduce systolic blood pressure by 20 (mmHg) millimetre of…

Incidentaloma (Conns’ syndrome) is a disease of the adrenal glands involving excess production of aldosterone & patient usually presents with clinical features of hypokalemia and hypertension. Atypical clinical presentations with combination of normotension and normokalemia are described in few cases. In this case report patient presented with abdominal pain and essential hypertension only. To rule out other pathology Ultrasonography was performed & underlying adrenal adenoma was found.…

Why is this drug used? Lisinopril is used to treat heart failure, high blood pressure, and to assist in the survival in patients who may have had a heart attack. It is in a class of drugs called Angiotensin Converting Enzyme blockers (ACE). This drug works by reducing certain chemicals that squeeze the blood vessels, so that the blood can flow smoother and the heart can pump the blood better. (U.S. National Library of Medicine [NLM], 2015) Dosage Forms It is in a tablet form of 2.5 mg, 5 mg,…

Should Adrenaline Fatigue Patients be Tested for Iodine Deficiency? In the human body, iodine deficiency and adrenaline fatigue are correlated. This phenomenon is not new to the world of medicine. Yet, it is largely ignored, inadequately researched, and poorly understood by scientists, physicians, nutritionists, and medical practitioners all across the globe. This article focuses on the link between iodine deficiency and adrenaline fatigue. It also stresses on the need for adequate iodine in…

blocker, to help lower his blood pressure by inhibiting calcium into myocardial cells. By inhibiting calcium into the cells it inhibits excitation-contraction. He is also taking lisinopril, an ACE inhibitor, that blocks the conversion of angiotensin I to angiotensin II (a vasoconstrictor). The ACE inhibitor helps keep vessels open, lowering blood pressure. Aspirin is used to thin the blood by decreasing platelet aggregation (Vallerand). Keeping blood thin, helps prevent MIs. With CAD he is…

Stroke What is stroke? Stroke is characterized by brain damage due to bleeding or a loss of blood supply to the brain. This often leads to long-term disability caused by symptoms such as paralysis, trouble swallowing and speaking, and loss of vision. It is one of the leading causes of death in the United States. In fact, people with stroke have a very high risk of developing a heart attack. Due to the importance of this condition, it is critical that patients understand its causes, symptoms,…
