Here's the British Government's recommendation for people with both conditions:
Table 2. Initial treatment recommendations in hypertensive people with no degree of nephropathy |
First choice in heart failure, left ventricular dysfunction and diabetes.
Angiotensin II receptor antagonists (AIIRAs)
Alternative option for someone who cannot tolerate an ACE inhibitor.
A low dose of thiazide is first choice in most people, especially those over 60 years.
Cardioselective agents are preferred. First choice if angina or history of myocardial infarction. Those that are appropriately licensed may be considered in people with heart failure.
Calcium-channel blockers (dihydropyridines)
Long-acting dihydropyridines are an alternative option in elderly people, especially those with isolated systolic hypertension. Consider as an alternative option in angina if a beta-blocker is not tolerated or is contraindicated.
Calcium-channel blockers (rate-limiting)
Alternative option for someone with angina if a beta-blocker is not tolerated or is contraindicated.
An option in someone with prostatism, and to be considered for someone with dyslipidaemia.

There seems to be agreement among physicians that diuretic usage is a good idea EVEN IF the risk of diabetes is increased. Most seem to feel that the increase in blood glucose is not significant enough to warrant discontinuation.
