MTP 006-Heart Failure Revisited Clinical questions to be addressed: What is the real distinction between systolic and diastolic heart failure? What are the stages of heart failure, and how does this alter medical management in these patients? What do the clinical trials of device therapy (biventricular pacing, defibrillator therapy, and the combination) tell us? What are the data on driving in patients who have arrhythmias? Which arrhythmias put a motorist/pedestrian at high risk? After implantation of pacemakers and defibrillators, what time period should elapse before driving can commence and what are the data to support this? What is the impact of renal insufficiency and anemia in patients with heart failure?
