Meanwhile, reports in the prestigious

Lancet

and

British

Medical Journal

differ over the BP targets recommended.

What guidelines in the world tend to agree on, he said, was

that treating with two drugs as initial therapy was the way

to go. Just two drugs in a single tablet has already improved

compliance by 21%. If a patient was above a certain level of

risk, they should also be on a statin, regardless of cholesterol

levels, until at least 80 years of age, he added.

Prof Poulter’s conclusions fromtheACE inhibitors vsARB

controversy in managing hypertension are that individual

trial data and meta-analyses are relatively consistent in

showing the superiority of ACE inhibitors. ARBs are better

tolerated but do not reduce mortality rate or cardiac events as

well as ACE inhibitors and should be used if patients cough

on ACE inhibitors. Prof Poulter concluded his presentation

with a telling cartoon of an obese man, with a frothy pint of

beer in one hand and a cigarette butt in his mouth, sticking

his hand through a hole in a wall, on the other side of which,

an unseeing doctor measures his BP and puts pills in an

outstretched palm.

Session moderator, Prof Sajidah Khan, an interventional

cardiologist at the Gateway Private Hospital in Umhlanga,

said that in the very country that most funds prevention

(North America), the sale of ultra-processed foods this year

rose by 2.3% compared to a 71% increase in Africa and

Eastern countries. Simultaneously, the revenue growth for the

world’s biggest tobacco retailer, Philip Morris, rose by 2.8%.

It was therefore unsurprising that 80% of all cardiovascular

disease occurs in lower- to middle-income countries. The

damaging myths about statins paled by comparison with this.

Prof Brian Rayner, head of the Division of Nephrology

and Hypertension at the Groote Schuur Hospital and

University of Cape Town, said a three-pill regimen would

address huge unmet needs in South Africa and the continent.

He said up to 90% of hypertensive South African patients

remain untreated and agreed with Prof Poulter that the

American guidelines, ‘have set us back and created confusion

in the definition of hypertension – there’s a big difference

between a target and the definition,’ he added.
