From the Guidelines
A patient with a history of vascular dementia and ischemia likely has heart failure with reduced ejection fraction (HFrEF) due to the underlying ischemic etiology. This type of heart failure occurs when the heart muscle is unable to contract effectively, resulting in reduced cardiac output and increased morbidity and mortality [ 1 ]. The connection between vascular dementia, ischemia, and HFrEF stems from shared risk factors and pathophysiology involving microvascular dysfunction, endothelial damage, and chronic inflammation. These patients often have a history of hypertension, diabetes, coronary artery disease, and other vascular conditions that contribute to both their cognitive impairment and cardiac dysfunction.
Key Points to Consider
- The patient's history of ischemia suggests an ischemic etiology for their heart failure, which is more commonly associated with HFrEF [ 1 ].
- Vascular dementia is a type of dementia caused by reduced blood flow to the brain, which can be related to the same vascular risk factors that contribute to HFrEF [ 1 ].
- Management of HFrEF typically includes controlling hypertension with ACE inhibitors or ARBs, using beta-blockers for symptom relief, and addressing underlying vascular risk factors through statins, antiplatelet therapy, and lifestyle modifications.
- The prognosis for these patients requires careful monitoring as both their cardiac and cognitive conditions can complicate treatment adherence and overall management.
Important Considerations for Management
- Controlling hypertension and addressing underlying vascular risk factors are crucial in managing both HFrEF and vascular dementia [ 1 ].
- The use of diuretics and other medications should be carefully considered in patients with HFrEF and vascular dementia, as they can have complex interactions and side effects [ 1 ].

From the Research
Heart Failure Types
- Heart failure with reduced ejection fraction (HFrEF) is a common type of heart failure, accounting for approximately 50% of cases 2.
- HFrEF occurs when the left ventricular ejection fraction (LVEF) is 40% or less, accompanied by progressive left ventricular dilatation and adverse cardiac remodeling 2.
Relevant Patient Factors
- A history of vascular dementia and ischemia may indicate a higher likelihood of HFrEF, as cardiac ischemia is a common cause of HFrEF 3.
- The presence of ischemia suggests that the patient may have HFrEF, which is often caused by cardiac ischemia 3.
Diagnosis and Treatment
- Assessment for heart failure begins with obtaining a medical history and physical examination, and diagnosis is central to identifying left ventricular systolic dysfunction with LVEF of 40% or less as measured by echocardiography 2.
- Treatment strategies for HFrEF include the use of diuretics, β-blockers, angiotensin receptor-neprilysin inhibitors, angiotensin-converting enzyme inhibitors, and angiotensin receptor blockers, as well as device therapies such as cardiac resynchronization therapy and implantable cardiac defibrillators 2, 4, 5.
