A Patient with a History of Myocardial Infarction
According to Dunn, (2013), the presence of hypertension is initially established and the
patient’s clinical and hemodynamic status is assessed. In case evidence of heart failure is found,
the therapy initiated should be aimed at reducing vascular resistance as well as ventricular filling
pressure. Pure arteriolar dilators like minoxidil and hydralazine should be avoided due to their
capacity to reflexively increase the heart rate and myocardial contractility as shown in Dunn,
(2013). Nitroprusside and nitroglycerine have venodilating properties and have minimal
reflexive impact, they should be considered. In case heart failure is not detected, a less
aggressive therapy is considered to control arterial pressure. Any observed elevations of pressure
should be treated using nitroglycerine and nitroprusside. Dunn, (2013) continues to show how
oral antihypertensive drugs should be administered with caution during the post infarction state.

A Patient with Atrial Fibrillation
Widimský, (2012) shows that for hypertensive patients presenting with AF, the primary
consideration is achieving normal BP levels. This is attributed to the high risk for CV,
particularly stroke. Although antihypertensive agents are administered for reducing the risk of
AF by decreasing blood pressure, there are other individual mechanisms like the impact on
sympathetic nervous system. As shown in Widimský, (2012), the ultimate goal will be reducing
blood pressure. Renin angiotensin aldosterone system blockers are administered for reducing the
risk for AF. This is especially important for high risk patients, especially ones presenting with
