Key result
Patients with renovascular hypertension had a consistently higher cardiac index compared to those with essential hypertension, despite both groups having increased total peripheral resistance.

Do systemic hemodynamic profiles differ between patients with essential hypertension and renovascular hypertension?
Renovascular hypertension is characterized by a higher cardiac output compared to essential hypertension, challenging the notion that increased total peripheral resistance is the sole systemic hemodynamic abnormality in all forms of hypertension.
Fröhlich et al. (1967) conducted an observational in Essential and Renovascular Hypertension (n=45). Renovascular hypertension vs. Essential hypertension was evaluated on Systemic hemodynamic measurements (cardiac index, total peripheral resistance). Patients with renovascular hypertension had a consistently higher cardiac index compared to those with essential hypertension, despite both groups having increased total peripheral resistance.
