ventricular ejection fractions การใช้

• Consequently, ventricular ejection fraction and contractile function is reduced, leading to diastolic dysfunction.
• Some risk factors for death include age, left ventricular ejection fraction may increase the predictive power.
• The function of the myocardium is also evaluated by calculating the left ventricular ejection fraction ( LVEF ) of the heart.
• Radionuclide ventriculography gives a much more precise measurement of left ventricular ejection fraction ( LVEF ) than a transthoracic echocardiogram ( TTE ).
• The patients were characterized by a disease severity of NYHA class III and a left ventricular ejection fraction of e " 25 %.
• In normal subjects, the left ventricular ejection fraction ( LVEF ) should be about 50 % ( range, 50-80 % ).
• A patient is said to have diastolic dysfunction if he has signs and symptoms of heart failure but the left ventricular ejection fraction is normal.
• These patients will have left atrial enlargement, and many will have a reduced left ventricular ejection fraction that indicates a combination of systolic and diastolic dysfunction.
• Approximately half of patients with severe symptomatic mitral regurgitation are denied surgery due to factors such as advanced age, co-morbidity, or decreased left ventricular ejection fraction.
• In addition to decreased left ventricular ejection fraction, studies indicate that patients with TIC may have a smaller left ventricular end-diastolic dimension compared to patients with idiopathic dilated cardiomyopathy.
• After four months, significant enhancements were found in ventricular ejection fraction, cardiac geometry, coronary blood flow reserve, and myocardial viability ( Shantsila, Watson, & Lip ).
• Increased risk of heart failure ( RR = 5.11 ) and decline in left ventricular ejection fraction ( RR = 1.83 ) were seen in these trials as well.
• Furthermore, patients with a positive response had lower left ventricular ejection fractions and stroke volumes, higher left ventricular filling pressure, higher mean pulmonary arterial, and higher right atrial pressures.
• Narrowly defined, diastolic failure has often been defined as " heart failure with normal systolic function " ( i . e . left ventricular ejection fraction of 60 % or more ).
• In the United States, Kadcyla carries black box warnings for liver toxicity, heart damage ( reduction in left ventricular ejection fraction ), and fetal harm if given to pregnant women.
• The MUGA scan was first introduced in the early 1970s and quickly became accepted as the preferred technique for measurement of left ventricular ejection fraction ( LVEF ) with a high degree of accuracy.
• Following long-term observation, the study concluded that CCM improved quality of life, exercise tolerance, NYHA class, left ventricular ejection fraction ( LVEF ) and brain natriuretic peptide ( BNP ) levels.
• As of 2016 pertuzumab had not been studied in people with a left ventricular ejection fraction value of d " 50 % normal, a prior history of congestive heart failure, or conditions that could impair left ventricular function like uncontrolled hypertension, recent heart attacks, or serious cardiac arrhythmia.
• Criteria for the classification of patients with left ventricular systolic heart failure include the severity of the disease based on functional parameters ( NYHA classification ), the average percentage of blood volume ejected by the left ventricle with each heart beat ( left ventricular ejection fraction or LVEF ) and the duration of the QRS complex seen in the electrocardiogram ( ECG ).
• The decision to anticoagulate people with HF, typically with left ventricular ejection fractions < 35 % is debated, but generally, people with coexisting atrial fibrillation, a prior embolic event, or conditions which increase the risk of an embolic event such as amyloidosis, left ventricular noncompaction, familial dilated cardiomyopathy, or a thromboembolic event in a first-degree relative.
