WebThe main pathophysiology of heart failure is a reduction in the efficiency of the heart muscle, through damage or overloading. As such, it can be caused by a wide number of conditions, including myocardial infarction (in which the heart muscle is starved of oxygen and dies), hypertension (which increases the force of contraction needed to pump blood) …

WebNormal heart sounds are associated with heart valves closing: First heart sound. The first heart sound, or S 1, forms the "lub" of "lub-dub" and is composed of components M 1 (mitral valve closure) and T 1 (tricuspid valve closure). Normally M 1 precedes T 1 slightly. It is caused by the closure of the atrioventricular valves, i.e. tricuspid and mitral (bicuspid), at …

WebHeart failure with preserved ejection fraction (HFpEF) is a form of heart failure in which the ejection fraction – the percentage of the volume of blood ejected from the left ventricle with each heartbeat divided by the volume of blood when the left ventricle is maximally filled – is normal, defined as greater than 50%; this may be measured by echocardiography or …

WebMyocardial infarction (MI) refers to tissue death of the heart muscle caused by ischaemia, the lack of oxygen delivery to myocardial tissue.It is a type of acute coronary syndrome, which describes a sudden or short-term change in symptoms related to blood flow to the heart. Unlike the other type of acute coronary syndrome, unstable angina, a myocardial …

WebLifestyle changes. People with congestive heart failure (CHF) are educated to undertake various non-pharmacological measures to improve symptoms and prognosis.Such measures include: Moderate physical activity, when symptoms are mild or moderate; or bed rest when symptoms are severe.; If sleep apnea is identified, treat with CPAP, BiPAP, …

WebRespiratory failure results from inadequate gas exchange by the respiratory system, meaning that the arterial oxygen, carbon dioxide, or both cannot be kept at normal levels.A drop in the oxygen carried in the blood is known as hypoxemia; a rise in arterial carbon dioxide levels is called hypercapnia.Respiratory failure is classified as either Type 1 or …

WebThere are few contraindications to bone marrow examination. It is important to note that thrombocytopenia or bleeding disorders are not contraindications as long as the procedure is performed by a skilled clinician. Bone marrow aspiration and biopsy can be safely performed even in the setting of extreme thrombocytopenia (low platelet count). If there is …

WebMitral regurgitation (MR), also known as mitral insufficiency or mitral incompetence, is a form of valvular heart disease in which the mitral valve is insufficient and does not close properly when the heart pumps out blood. It is the abnormal leaking of blood backwards – regurgitation from the left ventricle, through the mitral valve, into the left atrium, when the …
