Taylor, N C, Barber, R W, Crossland, P, English, T A, Wraight, E P, Petch, M C
The effect of coronary artery bypass grafting on global left ventricular ejection fraction and regional contraction was studied in 56 consecutive patients with chronic stable angina pectoris by means...
Stone, D L, Petch, M C, Verney, G I, Dixon, A K
In two patients aortic dissection occurred as a late complication of aortic valve replacement and caused superior vena caval obstruction. The dissection and superior vena caval obstruction were...
Arrhythmias after coronary bypass surgery.
Ormerod, O J, McGregor, C G, Stone, D L, Wisbey, C, Petch, M C
Ninety patients undergoing coronary bypass surgery were studied prospectively by bedside and subsequent ambulatory electrocardiographic monitoring to investigate the incidence, possible causes, and...
Acute haemodynamic effects of oral prenalterol in severe heart failure.
Petch, M C, Wisbey, C, Ormerod, O, Scott, C, Goodfellow, R M
The acute haemodynamic effects of oral prenalterol were studied in 14 patients with severe heart failure (NYHA class III) due to ischaemic heart disease. All had received treatment with digoxin,...
Computed tomography in patients with hypertrophic cardiomyopathy.
Stone, D L, Petch, M C, Verney, G I, Dixon, A K
Computed tomography was undertaken in nine patients (age range 33-69 (mean 48.7) years) with hypertrophic cardiomyopathy. The ventricular septum was demonstrated in each patient and shown to be...
Glover, D R, Wathen, C G, Murray, R G, Petch, M C, Muir, A L, Littler, W A

Uptake of catecholamines by human cardiac muscle in vitro.
Noradrenaline uptake was studied using heart muscle from 102 patients undergoing cardiac surgery. Slices of right atrium were incubated in Krebs-Henseleit solution containing 1.3 x 10(-7) M...
Concentration of catecholamines in human cardiac muscle.
A trihydroxyindole fluorescent technique was used to measure the concentration of catecholamines in heart muscle taken from 42 patients undergoing open heart surgery. Noradrenaline was the dominant...
