Targeting Microvascular Dysfunction in Young Hypertensive Patients

• To be eligible for the study, all of the following criteria must be met:

  • All patients must have a diagnosis of essential hypertension with off treatment systolic pressure >140 mmHg and/or diastolic pressure >90 mmHg, measured at rest in the seated position on at least two separate occasions, at least 2 weeks apart.
  • Patients will be \< 50 years for men and \< 60 years for women.
  • Female patients of childbearing potential must be using a medically accepted means of contraception (that is, interuterine device, oral contraceptive, implant, DepoProvera or barrier devices). Female patients of childbearing age will be screened with a pregnancy test.
  • Patients will be typically already on antihypertensive therapy.
  • Patients must have a level of understanding sufficient to complete all tests and examinations required by the protocol and are able to understand and give informed consent.

Exclusion Criteria:

• Patients will be excluded from the study if they meet any of the following criteria:

  • A history of diabetes mellitus, coronary artery or cerebrovascular disease, hypertensive retinopathy, hypertensive nephropathy, left ventricular hypertrophy or hyperlipidaemia warranting treatment as defined by the latest NICE guidelines which recommend an age based treatment strategy rather than one driven purely by lipid levels in isolation.
  • Abnormal baseline liver function (defined as AST or ALT > 3 times upper limit of normal), raised baseline creatinine kinase (CK) (defined as CK > 200 mmol/L), severe renal impairment (defined as estimated glomerular filtration rate (eGFR) \< 30 mls/minute) or previous adverse event relating to either an ARB or statin in the past.
  • Female patients will be excluded if they are pregnant, intend to be pregnant or are lactating. Female patients of childbearing age will be screened with a pregnancy test.
