Abnormalities in Cardiopulmonary Exercise Testing Ventilatory Parameters in Heart Failure: Pathophysiology and Clinical Usefulness

Abstract Heart failure (HF) is a complex syndrome characterized by myocardial dysfunction, derangement of multiple organ systems and poor outcome. Out of several markers of severity, abnormalities in exercise ventilation (VE) offer relevant insights into the pathophysiology of dyspnea, lung gas exch...

520			\|a Abstract Heart failure (HF) is a complex syndrome characterized by myocardial dysfunction, derangement of multiple organ systems and poor outcome. Out of several markers of severity, abnormalities in exercise ventilation (VE) offer relevant insights into the pathophysiology of dyspnea, lung gas exchange, and control of ventilation and are now recognized as meaningful indicators of disease severity and prognosis. Ventilation inefficiency, identified as an increased slope of VE vs carbon dioxide production ($ VCO_{2} $) recognizes as major determinants an increased waste ventilation due to enhanced dead space, early occurrence of lactic acidosis, and an abnormal chemoreflex and/or metaboreflex activity. In some cases of HF, especially associated with advanced hemodynamic and neural deregulation, an exercise oscillatory ventilatory (EOV) pattern may occur. According to an increasing number of studies, EOV identifies the 15–30 % of higher-risk HF patients requiring aggressive treatment and provides an even more robust prediction of outcome compared to VE/$ VCO_{2} $ slope. Overall, a refined prevalence definition and more comprehensive use of these markers in a clinical environment and in future interventional trials seem challenging for the years to come.

Out of several markers of severity, abnormalities in exercise ventilation (VE) offer relevant insights into the pathophysiology of dyspnea, lung gas exchange, and control of ventilation and are now recognized as meaningful indicators of disease severity and prognosis. Ventilation inefficiency, identified as an increased slope of VE vs carbon dioxide production ($ VCO_{2} $) recognizes as major determinants an increased waste ventilation due to enhanced dead space, early occurrence of lactic acidosis, and an abnormal chemoreflex and/or metaboreflex activity. In some cases of HF, especially associated with advanced hemodynamic and neural deregulation, an exercise oscillatory ventilatory (EOV) pattern may occur. According to an increasing number of studies, EOV identifies the 15–30 % of higher-risk HF patients requiring aggressive treatment and provides an even more robust prediction of outcome compared to VE/$ VCO_{2} $ slope. Overall, a refined prevalence definition and more comprehensive use of these markers in a clinical environment and in future interventional trials seem challenging for the years to come.

abstract	Abstract Heart failure (HF) is a complex syndrome characterized by myocardial dysfunction, derangement of multiple organ systems and poor outcome. Out of several markers of severity, abnormalities in exercise ventilation (VE) offer relevant insights into the pathophysiology of dyspnea, lung gas exchange, and control of ventilation and are now recognized as meaningful indicators of disease severity and prognosis. Ventilation inefficiency, identified as an increased slope of VE vs carbon dioxide production ($ VCO_{2} $) recognizes as major determinants an increased waste ventilation due to enhanced dead space, early occurrence of lactic acidosis, and an abnormal chemoreflex and/or metaboreflex activity. In some cases of HF, especially associated with advanced hemodynamic and neural deregulation, an exercise oscillatory ventilatory (EOV) pattern may occur. According to an increasing number of studies, EOV identifies the 15–30 % of higher-risk HF patients requiring aggressive treatment and provides an even more robust prediction of outcome compared to VE/$ VCO_{2} $ slope. Overall, a refined prevalence definition and more comprehensive use of these markers in a clinical environment and in future interventional trials seem challenging for the years to come.

According to an increasing number of studies, EOV identifies the 15–30 % of higher-risk HF patients requiring aggressive treatment and provides an even more robust prediction of outcome compared to VE/$ VCO_{2} $ slope. Overall, a refined prevalence definition and more comprehensive use of these markers in a clinical environment and in future interventional trials seem challenging for the years to come.

Out of several markers of severity, abnormalities in exercise ventilation (VE) offer relevant insights into the pathophysiology of dyspnea, lung gas exchange, and control of ventilation and are now recognized as meaningful indicators of disease severity and prognosis. Ventilation inefficiency, identified as an increased slope of VE vs carbon dioxide production ($ VCO_{2} $) recognizes as major determinants an increased waste ventilation due to enhanced dead space, early occurrence of lactic acidosis, and an abnormal chemoreflex and/or metaboreflex activity. In some cases of HF, especially associated with advanced hemodynamic and neural deregulation, an exercise oscillatory ventilatory (EOV) pattern may occur. According to an increasing number of studies, EOV identifies the 15–30 % of higher-risk HF patients requiring aggressive treatment and provides an even more robust prediction of outcome compared to VE/$ VCO_{2} $ slope. Overall, a refined prevalence definition and more comprehensive use of these markers in a clinical environment and in future interventional trials seem challenging for the years to come.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Heart failure</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Preserved ejection fraction</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Pulmonary hypertension</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Exercise ventilation inefficiency</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Prognosis</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Current heart failure reports</subfield><subfield code="d">Philadelphia, Pa. : Current Science, 2004</subfield><subfield code="g">11(2014), 1 vom: 10.
