Persistent thallium-201 defect: can clinical, electrocardiographic and exercise hemodynamic variables predict defect normalization with reinjection?

abstract：:Valsartan is a specific angiotensin II receptor antagonist with high selectivity for the AT(1) receptor subtype. After oral administration of single or repeated once-daily doses, valsartan 40-80 mg inhibits the pressor response to angiotensin II for 24 hours. In patients with mild-to-moderate hypertension, efficacy of...
