[PMID: 27836303 DOI: 10.1016/j.ijcard.2016.10.041] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2016] [Revised: 10/10/2016] [Accepted: 10/14/2016] [Indexed: 10/20/2022]
Abstract
BACKGROUND Left ventricular diastolic dysfunction (LVDD) is closely related to heart failure with preserved ejection fraction (HFpEF), while the prevalence and correlates of either LVDD or HFpEF in elderly population remain largely unknown. METHODS The study was performed in 1274 community residents (769 women, aged ≥65years) who participated in the Shanghai Heart Health Study. Demographic, laboratory and echocardiographic data were obtained to analyze correlates of LVDD and HFpEF using univariate and multivariate Logistic analysis. RESULTS LVDD was detected in 31.9% (406/1274) residents and it was significantly higher in women than in men (34.2% vs. 28.3%, P=0.027). HFpEF prevalence was 2.8% (35/1274), and increased with aging in the whole cohort. For residents with left ventricular ejection fraction ≥50% and normal-sized ventricular cavity, female sex (odds ratio [OR] 1.69, 95% confidence interval [CI] 1.24-2.29), heart rate (OR 0.76, 95% CI 0.68-0.86), atrial fibrillation (OR 7.37, 95% CI 3.13-17.36), hypertension (OR 1.32, 95% CI 1.00-1.75), N-terminal pro-B type natriuretic peptide (OR 2.33, 95% CI 1.50-3.61) and high-sensitivity troponin T (hs-TnT) (OR 1.90, 95% CI 1.12-3.23) were independent correlates of asymptomatic LVDD. While age (OR 1.44, 95% CI 1.01-2.06), heart rate (OR 0.66, 95% CI 0.47-0.93) and hs-TnT (OR 4.37, 95% CI 1.46-13.12) were independently related to HFpEF. CONCLUSIONS LVDD is common in this community elderly population, and HFpEF is also not rare. Different factors played roles in different stages of HFpEF. Future studies are warranted to explore the predictors of LVDD and HFpEF in the community elderly.

A Comprehensive Genomic Analysis Reveals the Genetic Landscape of Mitochondrial Respiratory Chain Complex Deficiencies. PLoS Genet 2016; 12:e1005679. [PMID: 26741492 PMCID: PMC4704781 DOI: 10.1371/journal.pgen.1005679] [Citation(s) in RCA: 214] [Impact Index Per Article: 26.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2015] [Accepted: 10/27/2015] [Indexed: 02/07/2023] Open
Abstract
Mitochondrial disorders have the highest incidence among congenital metabolic disorders characterized by biochemical respiratory chain complex deficiencies. It occurs at a rate of 1 in 5,000 births, and has phenotypic and genetic heterogeneity. Mutations in about 1,500 nuclear encoded mitochondrial proteins may cause mitochondrial dysfunction of energy production and mitochondrial disorders. More than 250 genes that cause mitochondrial disorders have been reported to date. However exact genetic diagnosis for patients still remained largely unknown. To reveal this heterogeneity, we performed comprehensive genomic analyses for 142 patients with childhood-onset mitochondrial respiratory chain complex deficiencies. The approach includes whole mtDNA and exome analyses using high-throughput sequencing, and chromosomal aberration analyses using high-density oligonucleotide arrays. We identified 37 novel mutations in known mitochondrial disease genes and 3 mitochondria-related genes (MRPS23, QRSL1, and PNPLA4) as novel causative genes. We also identified 2 genes known to cause monogenic diseases (MECP2 and TNNI3) and 3 chromosomal aberrations (6q24.3-q25.1, 17p12, and 22q11.21) as causes in this cohort. Our approaches enhance the ability to identify pathogenic gene mutations in patients with biochemically defined mitochondrial respiratory chain complex deficiencies in clinical settings. They also underscore clinical and genetic heterogeneity and will improve patient care of this complex disorder. Mitochondria play a crucial role in ATP biosynthesis and comprise proteins encoded in both the nuclear and mitochondrial genomes. Although more than 250 mitochondrial disease-causing genes have been reported, the exact genetic causes in patients remain largely unknown. Here, we aimed to provide further insights into the pathogenic mechanisms of mitochondrial disorders. We investigated the genes encoded in the nuclear and mitochondrial genomes using comprehensive genomic analysis in 142 patients with mitochondrial respiratory chain complex deficiencies. We identified 3 novel disease-causing mitochondria-related genes (MRPS23, QRSL1, and PNPLA4) as well as other disease-causing genes and novel pathogenic mutations in known mitochondrial disease-causing genes. All pathogenic mutations in this study are validated by genetic and/or functional evidence. Our findings, including the achievement of firm genetic diagnoses for 49 of 142 patients (34.5%), were higher than the general diagnosis rate of approximately 25% and demonstrated the value of comprehensive genomic analysis. Accordingly, we have shed light on the genetic heterogeneity underlying mitochondrial disorders.
