Final answer:
ACE inhibitors should generally be avoided in patients with a systolic blood pressure less than 100 mmHg, but the decision depends on individual patient characteristics.
Step-by-step explanation:
Angiotensin-Converting Enzyme Inhibitors (ACE-I) should generally be avoided in patients with a systolic blood pressure (SBP) less than 100 mmHg. ACE inhibitors can further decrease blood pressure, potentially causing hypotension. However, the decision on whether to use ACE inhibitors in patients with SBP less than 100 mmHg depends on individual patient characteristics, such as the presence of other medical conditions or medications. It is important to consult with a healthcare professional to determine the appropriate treatment plan for patients with low blood pressure.
