Heart Failure affects 5.3 millions Americans

Nearly 50% of these are women

Heart failure contributes 35% of the total female cardiovascular disease mortality

Despite this fact, HF in women remains a poorly recognized syndrome and has not received the samepublic awareness as coronary artery disease

What is the response to CRT in women ?

► Analysis of previous large CRT Trials

► Few studies addressing this issue

Page 10: Tenth International Symposium HEART FAILURE  & Co. CARDIOLOGY SCIENCE UPDATE

The Multicenter InSync Randomized Clinical Evaluation (MIRACLE) was a prospective, randomized, double-blinded study

A total of 453 pts ( 32%women) randomized to either CRT or a control group.

The Impact of Age and Gender on Cardiac Resynchronization Therapy Outcome

When stratified by the etiology of the underlying cardiomyopathy, ischemic women appear to have a worse long-term outcome than all other groups

CRT Trials and observational studies show discordant results

However a gender related difference in response to CRT seems to occur

It is not surprising since there are many reasons why male and female hearts are not the same

CRT: vi è un vantaggio maggiore nelle donne?

Al momento attuale la scarsa rappresentazione delle donne negli studi sulla terapia cardiaca resincronizzante fa si che ancora non vi siano chiare evidenze su un loro maggior beneficio

tuttavia

Le particolari caratteristiche dello scompenso cardiaco ed in particolare i diversi meccanismi che modulano il rimodellamento ventricolare nelle done rappresentano importanti presupposti per una loro migliore risposta
