What are the morbidity and mortality rates for myocardial resection?
In the study of 245 patients, ventricular reconstruction by myocardial resection was found to have an associated in-hospital mortality rate of 78.1%.
What factors can increase myocardial oxygen demand?
Heart rate and ventricular wall tension
Condition associated with servere chest pain and myocardial ischemia?
myocardial infarction
What does it mean to have intermittent high blood pressure nauseau palpitation occasional ventricular ectopic beats and feeling of collapse?
myocardial infarction
What is left ventricular perfusion?
Left Ventricular dysfunction-A condition in which the LEFT VENTRICLE of the heart was functionally impaired. This condition usually leads to HEART FAILURE; MYOCARDIAL INFARCTION; and other cardiovascular complications. Diagnosis is made by measuring the diminished ejection fraction and a depressed level of motility of the left ventricular wall.
Who performs myocardial resection?
Electrophysiologists, cardiac surgeons and cardiologists, specially trained in cardiac electrical signaling and ventricular reconstruction have undergone specific training in these procedures.
How do you punctuate the statement protracted high degree atrial ventricular block post inferior myocardial infraction an aortocornary bypass grafting?
I would put a comma after protracted and a hyphen between high and degree to make: Protracted, high-degree atrioventrical block post inferior myocardial infarction and aortocoronary bypass grafting.
How does tachycardia affect coronary artery perusion?
Tachycardia, or an elevated heart rate, can impair coronary artery perfusion by reducing the time available for diastolic filling when the heart relaxes. Since coronary blood flow primarily occurs during diastole, an increased heart rate shortens this phase, potentially leading to insufficient oxygen delivery to the myocardium. This can exacerbate conditions like ischemia, especially in individuals with existing coronary artery disease. Additionally, the increased myocardial oxygen demand associated with tachycardia can further strain the coronary circulation.
What is paroxysmal chest pain that results from ischemic myocardial tissue called?
Angina is a paroxysmal chest pain or pressure sensation associated with transient myocardial infarction.
What conditions are contraindicated for myocardial resection?
right heart failure, elevated left ventricular enddiastolic pressures, and pulmonary hypertension (high blood pressure in the circulation around the lungs).
What is homogeneous left ventricular myocardial perfusion?
Homogeneous left ventricular myocardial perfusion refers to a uniform distribution of blood flow throughout the left ventricle's myocardium during the cardiac cycle. This ideal state indicates that all regions of the heart muscle receive an adequate and equal supply of oxygen and nutrients, which is crucial for optimal cardiac function. Disruptions in this perfusion pattern can lead to areas of ischemia or reduced blood flow, potentially resulting in heart-related conditions. Evaluating myocardial perfusion is essential in diagnosing and managing various cardiovascular diseases.
Can spinal cord contusion cause ventricular fibrillation?
Spinal cord contusion primarily affects the spinal cord and may lead to various neurological deficits, but it does not directly cause ventricular fibrillation. Ventricular fibrillation is typically associated with cardiac issues, such as myocardial infarction or severe electrolyte imbalances. However, severe spinal injuries can lead to autonomic dysregulation, which may indirectly affect heart function. Therefore, while not a direct cause, complications from spinal cord injuries could potentially contribute to cardiac disturbances in some cases.
