Current evidence is limited to high-income countries. We examined the relationship between forced expiratory volume in 1\u2005second (FEV1), HF burden, and long-term clinical outcomes in a diverse multi-national HF cohort.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and Results<\/jats:title>\n                    <jats:p>In a sub-study within the multinational Global Congestive Heart Failure registry, which collected clinical data including spirometry from HF participants in 28 high-, middle-, and low-income countries, and followed for a median 3.8 (IQR 2.1, 5.0) years. Baseline FEV1 was transformed into z-scores standardized for age, sex, and height. The association between baseline FEV1 with all-cause mortality, cardiovascular (CV) deaths, and all-cause hospitalizations was examined.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Findings<\/jats:title>\n                    <jats:p>The analysis included 3359 HF participants (mean age 61.9 [SD 14.1] years, 66.4% males). Participants with lower FEV1 z-scores, even within the normal range (z-score&amp;gt;\u22122), showed increasing burden of HF, cardiac structural and functional impairment, and lower health-related quality of life. FEV1 z-score \u2264 \u22122 was independently associated with higher risks of all-cause (HR 2.20 [95%CI 1.61\u20133.01]), CV mortality (HR 2.45 [1.64\u20133.66]), and hospitalizations (HR 1.40 [1.12\u20131.74]). The effect sizes were comparable to those of other major prognostic factors. The association was consistent across populations from diverse socio-economic development, HF aetiology, HF types, and airflow obstruction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In a diverse, multi-national HF cohort, reductions in FEV1 were independently associated with higher HF burden and poor health outcomes.
