Geometry and Clinical Outcomes: 3-Year Follow-Up

Molecular and structural basis of

cardiac remodeling in heart failure

• CARDIAC INSULT

pressure overload

hypoxia, ischemia,

infection

• MEDIATORS

Increased wall stress

sub-endocardial ischemia

neurohormonal activation

cytokines/oxidative stress

iNOS expression

• MOLECULAR/CELLULAR

alterations in cardiomyocyte biology

cardiomyocyte loss (apoptosis, necrosis, auto-phagocytocis)

alterations in ECM turnover

• STRUCTURAL/ FUNCTIONAL

myocyte hypertrophy

myocyte slippage

cardiac fibrosis

cardiac dilatation

systolic/diastolic dysfunction

Neurohormonal model of HF

Ventricular remodeling

• Neurohormonal activation

– RAAS, SNS

• Increased cytokine

expression

• Immune and

inflammatory changes

• Altered fibrinolysis

• Oxidative stress

• Apoptosis

• Altered gene expression

• Energy starvation

Treatment of remodelling

Established

• Accepted approaches

(Improve prognosis)

• ACEi (or ARBs) or ARNI

• Beta blockers

• Aldo antagonists

• Ivabradine

• CRTs

• Revascularization in cases

with viable cardiac tissue

• Exercise training?

Questionable/Future

Individualised therapy

– BNP guided therapy?

– Pharmacogenetics?

Pharmacological interventions

– MMP inhibition ?

– Anabolics ?

Cell technology

– manipulation of healing

Conditions that increase the risk of

systemic embolization in patients

with LV thrombus are:

(1)severe congestive heart failure,

(2) diffuse LV dilatation and systolic dysfunction,

(3) previous embolization,

(4) advanced age,

(5) presence of LV protruding or mobile thrombi

(6) presence of AF

WARFARIN ANTI-PLATELETS

Summary- main interventions (I)

Medical treatment should contain:

• ACEi or ARBs or ARNI

• Beta blockers

• MRAs

• Ivabradine (in selected pts)

• ICD/CRT (in selected pts)

• Amiodarone (in selected pts)

• Anti-coagulant therapy (in the presence of thrombus and/or

history of embolic events and/or AF)

Summary- main interventions (II)

Surgical treatment should be considered:

In Large LV aneurysms / pseudoaneurysms

In progressive cardiac remodeling despite OMT

In LV aneurysms with recurrent severe arrhythmias (resistant to

drugs)

In LV aneurysms and recurrent embolic events despite medical

therapy
