| Abstract | BACKGROUND: Heterozygous familial hypercholesterolaemia (HeFH) is a severe autosomal dominant disease that is underdiagnosed, inadequately treated and has a severe long-term cardiovascular risk. Few studies have evaluated the long-term risk of high low-density lipoprotein cholesterol (LDL-C) concentrations. AIM: To evaluate long-term mortality in a large cohort of healthy subjects, according to LDL-C concentrations. METHODS: Based on a sample of 6956 subjects visiting a preventive cardiology department, we selected adult subjects without a personal history of cardiovascular disease. From 1995 to 2011, 4930 healthy subjects were examined and followed up until 31 December 2011. All-cause deaths were collected exhaustively. A Cox-based multivariable analysis evaluated long-term total mortality risk according to Dutch Lipid Clinic Network (DLCN) LDL-C concentrations. RESULTS: After a mean follow-up of 8.6 years, 123 all-cause deaths were recorded (cumulative mortality rate, 2.5%). In the final multivariable model, major risk factors such as age, sex, tobacco use and diabetes were significantly associated with mortality. After adjustment for age, sex, tobacco use, hypertension, diabetes and statin therapy, and in comparison with subjects with LDL-C<4 mmol/L (<155 mg/dL), subjects with LDL-C between 4 and <5 mmol/L (155 to <190 mg/dL) had a hazard ratio (HR) of 1.99 (95% confidence interval [CI] 1.31-3.02; P=0.001), subjects with LDL-C between 5 and <6.5 mmol/L (190 to <250 mg/dL) had an HR of 1.81 (95% CI, 1.06-3.02; P=0.030), subjects with LDL-C between 6.5 and<8.5 mmol/L (250 to <330 mg/dL) had an HR of 2.69 (95% CI, 1.06-6.88; P=0.038) and subjects with LDL-C ≥ 8.5 mmol/L (≥330 mg/dL) had an HR of 6.27 (95% CI, 0.84-46.57; P=0.073). After excluding patients on statins at baseline, subjects with LDL-C ≥ 8.5 mmol/L (≥330 mg/dL) had an HR of 8.17 (95% CI, 1.08-62.73; P=0.042). CONCLUSIONS: The severity of LDL-C elevation is associated with a higher risk of death in healthy subjects. DLCN LDL-C concentrations may be used in daily practice to identify patients with HeFH who warrant aggressive treatment. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
