- Indicate the correct order of the sequence of events occurring during congestive heart failure. Order the sentences (Hint: End with "g") This question is a great summary of what happens, in steps, in congestive heart failure. a. narrowed bicuspid valve makes the L atrium pump harder in order to "push" blood into the L ventricle through an opening that is too narrow. b. pressure of the extra, backed up blood in the lung creates pressure in the capillaries that begin to leak fluid into the lung. c. extra "left-over" blood in the atrium that has not descended into the ventricle after a beat has nowhere to go. d. congenital heart defect causes a narrowed bicuspid valve e. not all blood gets "pushed" from the L atrium to the L ventricle during a regular heart beat f. blood that backed up in the L atrium with nowhere to go backs up further, into the pulmonary veins and eventually into the lung g. the patient gets less oxygen with each breath, feels tired all the time and is…Choose the letter of the correct answer. STATEMENT A B C D Arterial blood pressure is independent of Blood volume Heart rate Blood viscosity Influx of calcium ions Identify the TRUE statement(s). There may be several correct answers. An increased cardiac output is reflected in an elevated diastolic pressure. An increased cardiac output is reflected in a decreased diastolic pressure. An increase in the force of contraction produces an elevated systolic pressure. An increase in the force of ventricular contraction produces decreased diastolic pressure. In the absence of compensations, the stroke volume will decrease when Blood volume increases Venous return increases Contractility increases Arterial blood pressure increases1. Mr. Garcia had a myocardial infarction. Explain what happened to his heart muscle and vascular system. What is a STEMII? 2. Mr. Garcia's chest pain resolved after two sublingual NTF at 3-minute intervals and 2 mg of IV morphine. In the cardiac catheterization lab he was "found to have a totally occluded distal right coronary artery and a 70% occlusion in the left circumflex coronary artery. The left anterior descending artery was patent. Angioplasty of the distal right coronary artery resulted in a patent infarct- related artery with near normal flow. A stent was left in place to stabilize the patient and limit infarct size. Left ventricular ejection fraction was normal at 42%, and a posterobasilar scar was present with hypokinesis." a. Explain angioplasty and stent placement. Define occluded occlusion. b. What is the purpose of this medical procedure?
