Which outcome results when systemic vascular resistance increases during heart relaxation?

💡 Explanation

Increased systemic vascular resistance hampers blood outflow during diastole leading to increased pressure referred to as afterload. Therefore diastolic blood pressure increases, because the cardiac muscle requires extreme pressure rather than influencing cardiac volume or output.

• A patient receives an oral medication that undergoes significant first-pass metabolism. If hepatic enzyme activity is substantially induced, which consequence follows?
• Why does severe acute pancreatitis often trigger acute kidney injury?
• Why does fever reduce the effectiveness of certain antibiotics?
• Why does botulinum toxin (Botox) injection cause localized muscle paralysis, even though action potentials still propagate along the motor neuron?
• If a catheter-associated biofilm infection exhibits increasing resistance to antibiotics, which consequence is most likely regarding horizontal gene transfer within the biofilm community?
• Why does focusing on a distant object after prolonged close-up work temporarily blur vision, involving the ciliary muscle?
