**8. Conclusions**

Cardiovascular diseases are the main cause of death around the world, and with the improvement in therapeutics leading to an increase of life expectancy it is probable that we will see increasing number of patients with HF. Also, prevalence of HF in the overall population ranges between 1 and 2% depending on the country. Therefore it is expected that the number of patients with AHF will continue rising after this review. Yet it is important keep in mind some concepts:

AHF: advanced heart failure

VAD: ventricular assist device

BTT: bridge to transplant BTC: bridge to candidacy BTD: bridge to decision

BTR: bridge to recovery DT: destination therapy

RAP: right atrial pressure

VO2: oxygen uptake

DCM: dilated cardiomyopathy

HCM: hypertrophic cardiomyopathy

CPET: cardiopulmonary exercise testing

VE/VC02: ventilation to carbon dioxide slope

INTERMACS: Interagency Registry for Mechanically Assisted Circulatory Support

Heart Transplant: Current Indications and Patient Selection

27

RCM: restrictive cardiomyopathy

RER: respiratory exchange ratio

SHFM: Seattle Heart Failure Model HFSS: heart failure survival score

6'WT: 6-minute walking test

PHT: pulmonary hypertension

PGF: primary graft failure

RVF: right ventricular failure

SPAP: systolic pulmonary arterial pressure

NYHA: New York heart association

MCS: mechanical circulatory support

STVAD: short-term ventricular assist device LTVAD: long-term ventricular assist device

PCWP: pulmonary capillary wedge pressure

CS: cardiogenic shock
