The Influence of Apical Aneurysm on Left Ventricular
Geometry and Clinical Outcomes: 3-Year Follow-Up
Using Echocardiography
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
Jugdutt BI. Circulation . 2003; 108:1395-1403.
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
LVADs (plus drugs)

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
