Left heart disease (LHD) may be associated with pulmonary hypertension determined by echocardiography, according to a study published in The American Journal of Cardiology.
In this retrospective study, the data of 310 patients ≥ 90 years of age (median age 92 years, 64% women) diagnosed with echocardiographic PH with normal left ventricular systolic function were reviewed using the transthoracic echocardiography database.
Echocardiography was used to determine the type of LHD: left-sided valve disease, left ventricular diastolic dysfunction, or left ventricular hypertrophy. The study’s primary outcome was all-cause death 2000 days after diagnosis.
In this cohort, 92% of patients had LHD. All-cause deaths occurred in 49% of the patients during the median follow up of 367 days (interquartile range, 39-1028 days). The following factors were found to be associated with mortality in a multivariable Cox regression analysis after adjusting for age: pericardial effusion (adjusted hazard ratio [aHR, 2.28; P<.001), right ventricular fraction area change < 35% (aHR, 2.31; P <.001), chronic obstructive pulmonary disease (aHR, 1.93; P =.001), serum albumin < 3.5 g/dL (aHR, 1.76; P =.001), and New York Heart Association class ≥ II (aHR, 1.73; P =.004).
Limitations of the study include its retrospective nature and the lack of evaluation of the relationship between the severity of comorbidities and PH and prognosis.
“[E]chocardiographic PH in patients ≥ 90 years of age was significantly associated with LHD,” concluded the study authors.
