Reni nangi otensi n system i nhi biti on i n pati ents with di abetes and PAD
Recent trials have highlighted the benefits of agents that block the renin-angiotensin -system in reducing cardiovascular events independent of their effects on blood pressure lowering. The HOPE study showed that long-term treatment with ramipril compared to placebo as add-on to other cardiovascular therapies confers significant reductions in morbidity and mortality among patients with CHD and asymptomatic patients with diabetes plus one other risk factor who do not have left ventricular...
Nature of Coronary Heart Disease in Diabetes
Case-control studies have demonstrated that diabetic patients with angiographically normal coronary arteries have smaller calibre coronary arteries than non-diabetic control subjects Mosseri etal., 1998 . Diabetes is an aetiological factor for the pathogenesis of coronary heart disease CHD and an adverse prognostic marker Kip etal., 1996 . Diabetic patients with coronary disease have a higher prevalence of other risk factors for CHD, and related vascular co-morbidity Kip etal., 1996 .When CHD...

Intermittent claudication
The term claudication is derived from the Latin word for limping. In the Framingham Study, diabetes was associated with two- to threefold excess risk of intermittent claudication for both sexes Brand etal., 1989 . Diabetics with intermittent claudication were at especially high risk for cardiovascular events. Claudicants present with a history of exercise-induced pain in the leg, typically affecting the calves, thighs or buttocks, depending on the location of occlusive arterial disease in the...

How do abnormalities of glucose and insulin metabolism affect the SNS and
There is some experimental evidence suggesting that neurohormonal systems are activated by diabetes and or insulin resistance, but this has not been demonstrated in patients with CHF. Hyperinsulinaemia increases circulating levels of norepinephrine and angiotensin II in normal volunteers Anderson etal., 1991 Reaven etal., 1996 Scherrer and Sartori, 1997 . Insulin resistance enhances the pressor response to angiotensin II in hypertensive patients Gaboury etal., 1994 . Infusion of FFAs in rats...
Rest pain and critical ischaemia
When PAD worsens, there is insufficient blood to supply the tissues of the leg even at rest and this often presents as continuous pain in the most distal part, namely the forefoot. Nerve ischaemia, manifesting as nocturnal rest pain and a form of neuritis, often precedes the onset of rest pain. It occurs at night when perfusion of the extremities is reduced. Patients often gain relief by hanging their foot over the side of the bed or walking for a few steps. This increases cardiac output,...
Risk factors for amputation
Studies have looked at various risk factors that contribute to lower extremity amputation in patients with diabetes. Poor glycaemic control is a major factor in the development of lower extremity amputation Lehto etal., 1996 and seems to be Diabetic Cardiolog Editors Miles Fisher and John J.

Management of Glycaemia The DIGAMI studies
The metabolic consequences of acute coronary syndromes include the release of epinephrine, glucagon and other counter-regulatory hormones. These antagonise the effects of insulin, and cause further worsening of insulin resistance. In the myocardium this insulin resistance favours the utilisation of free fatty acids, which may have a deleterious effect on myocardial function. In non-diabetic subjects, this may cause temporary hyperglycaemia, sometimes called 'stress hyperglycaemia', that...
