    Ker, James A.; Outhoff, Kim (OASIS, 2019-03)
    Globally more than 1 billion people have hypertension and it is predicted that because of ageing populations and increasing sedentary lifestyles, this figure will rise to about 1.5 billion by 2025. Elevated blood pressure ...
  • Burning issues in the prevention of heart failure 
    Ker, James A.; Outhoff, Kim (MedPharm Publications, 2020-08)
    Chronic heart failure is common, debilitating, and often the culmination of pervasive cardiovascular insults that systematically undermine the heart’s circulatory capacity and invoke counterproductive neuro-hormonal ...
