Cardiology (from greek καρδίᾱ kardiā, heart and -λογία-logia, study) is a branch of medicine dealing with disorders of the heart as well as parts of the circulatory systemthe field includes medical diagnosis and treatment of congenital heart defects, coronary artery disease, heart failure, valvular heart disease and electrophysiology. Physiological basis of treatment of hypertension biology essay high blood pressure can be defined as a sustained lift of systemic arterial force per unit area more than 140/90 mmhg in normal healthy person, arterial force per unit area is ranged around 100-140/70-90 mmhg. Heart failure (hf) is a syndrome resulting from the inability of the cardiac pump to meet the energy requirements of the body despite intensive work, the pathogenesis of the cardiac intracellular abnormalities that result from hf remains incompletely understood. Congestive heart failure: diagnosis, pathophysiology, therapy, and implications for respiratory care normal cardiopulmonary physiology and reducing the hyperadrenergic state the cornerstone of standing the pathophysiologic consequences of heart fail-ure and the potential treatments furthermore, an appreci.
Within the context of heart failure the uk national heart failure audit revealed that in-hospital mortality is lower when patient care is managed in specialist cardiology wards rather than general medical wards (78 % versus 132 %) 5 taken together these papers suggest that outcome is improved when in-patient care is provided by a specialised. Such an approach may generate new hypotheses, concepts and eventually novel treatments for the process of cardiac remodelling and heart failure, which should subsequently be tested in a physiological setting. Proper diagnosis of arrhythmias requires an electrocardiogram, which is used to evaluate the electrical activity of the heart depending on the severity of the arrhythmia, patients may experience dyspnea (shortness of breath), syncope (fainting), fatigue, heart failure symptoms, chest pain or cardiac arrest.
Heart failure and cardiac disease hypertension imaging and diagnostic testing intervention, surgery, transplantation contraction-excitation feedback in myocardium physiological basis and clinical relevance m j lab contraction-excitation feedback in myocardium physiological basis and clinical relevance m j lab circulation research. Heart failure is a clinical syndrome that results when the heart is unable to provide sufficient blood flow to meet metabolic requirements or accommodate systemic venous return this common condition affects over 5 million people in the united states at a cost of $10–38 billion per year. Esc heart failure is the open access journal of the heart failure association the journal aims to improve the understanding, prevention, investigation and treatment of heart failure molecular and cellular biology, pathology, physiology, electrophysiology, pharmacology, as well as the clinical, social and population sciences all form part of the discipline that is heart failure. Doctoral education in this department focuses on the study of prevention, measurement, and treatment of physiological and bio-behavioral responses to health, illness/disease and aging psycho-physiological interrelationships and interventions also are studied. Treatment of hypertension is based on age, sex, ethnic origin and physiological status both pharmacological and non pharmacological therapies are used to treatments pharmacological therapy is conducted by using one drug or drug combinations.
Multidisciplinary 7 the 2001 canadian cardiovascular society consensus guidelines update for strategies for the management of heart failure patients at high risk for the management and prevention of heart failure. Modern medicine appears to have met the challenge of these implications with regard to developing treatments that will cure most diseases including biology, stress, heart disease in women - research papers on heart disease in women discuss the number one killer of women in the united states. Aim: diastolic dysfunction is central to the development of heart failure to date, there is no effective treatment and only limited understanding of its molecular basis. Although psychological factors play an important role in coronary heart diseases (chd), it seems there is a need for more researches in this respect the present study aimed to review psychological factors, including depression, anxiety and stress related to etiology and prognosis of chd.
Biology of relaxin and potential beneficial effects in heart failure heart failure is a cardiac-renal-vascular-neurohormonal-inflammatory-ischemic-fibrotic disorder human data indicate that relaxin relieves systemic and renal vasoconstriction and increases vascular compliance, including normalization of high bp, ↓ pcwp, ↑ co, ↑ renal. Dickinson w richards, the contributions of right heart catheterization to physiology and medicine, with some observations on the physiopathology of pulmonary heart disease, american heart journal, 54, 2, (161), (1957. Heart failure (hf) is a complex clinical syndrome that can result from any functional or structural cardiac disorder that impairs the ventricle’s ability to fill.
Pathophysiology of heart failure, ventricular remodelling and the involved neurohumoral mechanisms are well-studied, and you shall get several papers on it on pubmed or google scholar books robbins and cotran: pathological basis of disease 9th edition. The oxford textbook of heart failure takes the reader from an understanding of the basic mechanisms of heart failure, through to an appreciation of the complexities of heart failure management and the improvements possible with good treatment. Heart failure specialists are investigating new strategies to detect heart transplant rejection, new drugs for heart failure and devices that continuously monitor heart pressures for better management of heart failure on an outpatient basis.
Arteriosclerosis, thrombosis, and vascular biology (atvb) journal home current issue heart failure vol 2, no 3 physiological replacement of t 3 improves left ventricular function in gd, raya te, bahl jj, goldman s studies on the use of thyroid hormone and a thyroid hormone analogue in the treatment of congestive heart failure ann. Heart failure is a very common disease that can have a high death rate despite advancements in treatment, the death rate has been increasing therefore, understanding the disease mechanism and its progression, common causes, risk factors, signs and symptoms, and treatments are very important. - congestive heart failure (chf) is defined as a clinical syndrome in which the heart fails to propel blood forward normally, resulting in congestion in the pulmonary and/or systemic circulation and diminished blood flow to the tissues due to reduced cardiac output. Treatment failure, on the other hand, may trigger a renewed cycle of grieving and distress the distress may be especially severe for patients living in western developed nations such as the united states, where the cultural assumption is that anyone who works hard and is persistent will succeed in achieving a goal.
It is a major risk factor for many common chronic diseases, such as heart failure, myocardial infarction, stroke, and end-stage kidney disease although the exact cause of essential hypertension is elusive, it is well established that increased vascular resistance plays a major pathophysiological role in the development of hypertension. Heart failure is a major cause of morbidity and mortality in contemporary societies although progress in conventional treatment modalities is making steady and incremental gains to reduce this disease burden, there remains a need to explore new and potentially therapeutic approaches. Heart failure: a companion to braunwald's heart disease, lewin chair and professor of medicine, cell biology, and physiology, chief, cardiovascular division, washington university school of medicine cardiologist-in-chief, treatment of heart failure with preserved ejection fraction. The cardiovascular biology journal club course is designed to highlight the advances in cardiovascular science and medicine that will soon form the foundation for novel diagnostic, prognostic and therapeutic approaches to treating heart disease.
