Long-term sex differences in atherosclerotic cardiovascular disease in individuals with heterozygous familial hypercholesterolaemia in Spain: a study using data from SAFEHEART, a nationwide, multicentre, prospective cohort study.

BACKGROUND: Sex differences in atherosclerotic cardiovascular disease (ASCVD) in familial hypercholesterolaemia have been reported but are not fully established. We aimed to assess sex differences in the risk of ASCVD and life-time burden of ASCVD in patients with heterozygous familial hypercholesterolaemia. METHODS: SAFEHEART is a nationwide, multicentre, long-term prospective cohort study conducted in 25 tertiary care hospitals and one regional hospital in Spain. Participants in the SAFEHEART study aged 18 years or older with genetically confirmed familial hypercholesterolaemia were included in our analysis. Data were obtained between Jan 26, 2004, and Nov 30, 2022. ASCVD and age at onset were documented at enrolment and at follow-up. Our aim was to investigate the differences by sex in the risk and burden of ASCVD in patients with heterozygous familial hypercholesterolaemia, over the study follow-up and over the life course. The SAFEHEART study is registered with ClinicalTrials.gov, NCT02693548. FINDINGS: Of the 5262 participants in SAFEHEART at the time of analysis, 3506 (1898 [54·1%] female and 1608 [45·9%] male participants) met the inclusion criteria and were included in the current study. Mean age was 46·1 years (SD 15·5) and median follow-up was 10·3 years (IQR 6·4-13·0). Mean on-treatment LDL-cholesterol at follow-up was 3·1 mmol/L (SD 1·4) in females and 3·0 mmol/L (1·5) in males. LDL-cholesterol reductions over time were similar in both sexes (1·39 mmol/L [95% CI 1·30-1·47] absolute reduction in females vs 1·39 mmol/L [1·29-1·48] in males; p=0·98). At enrolment, 130 (6·8%) females and 304 (18·9%) males (p<0·0001) had cardiovascular disease. During follow-up, 134 (7·1%) females and 222 (13·8%) males (p<0·0001) had incident cardiovascular events. Median age at first ASCVD event (mostly due to coronary artery disease) was 61·6 years (IQR 50·0-71·4) in females and 50·6 years (42·0-58·6) in males (p<0·0001). The adjusted hazard ratio for ASCVD in males compared with females during follow-up was 1·90 (95% CI 1·49-2·42) and for cardiovascular death was 1·74 (1·11-2·73). Major adverse cardiovascular disease event (MACE)-free survival from birth was lower in males than females (hazard ratio 3·52 [95% CI 2·98-4·16]; p<0·0001). Median MACE-free survival time was 90·1 years (95% CI 86·5-not estimable) in females and 71·0 years (69·2-74·6) in males. The age at which 25% of female participants have had a MACE event was 74·9 years, this figure was 55·5 years in male participants. INTERPRETATION: Our findings suggest that the burden and risk of ASCVD are markedly lower in females than males with familial hypercholesterolaemia. The impact of sex needs to be considered to improve risk stratification and personalised management in patients with heterozygous familial hypercholesterolaemia.

Persistence with long-term PCSK9 inhibitor treatment and its effectiveness in familial hypercholesterolaemia: data from the SAFEHEART study.

AIMS: Most heterozygous familial hypercholesterolaemia (FH) patients require intensive lipid-lowering therapy (LLT) including PCSK9 inhibitors (PCSK9is) to reach current low-density lipoprotein cholesterol (LDL-C) goals. Persistence with chronic treatment is important to reduce the burden of atherosclerotic cardiovascular disease. We analysed persistence, efficacy, and impact on quality of life (QoL) of PCSK9i in FH patients in clinical practice setting. METHODS AND RESULTS: Spanish Familial Hypercholesterolaemia Cohort Study (SAFEHEART) is an open, prospective study in genetically defined FH patients in Spain. Patients ≥18 years of age (n = 696, 46% females) on stable LLT treated with PCSK9i were analysed. Median LDL-C at starting PCSK9i was 145 mg/dL [interquartile range (IQR), 123-177], 3.8 mmol/L (IQR 3.2-4.6). After a median follow up of 3.7 years (IQR 2.3-4.8), 27 patients (4%) discontinued PCSK9i treatment: 5 temporarily (0.7%) and 22 permanently (3.2%). Persistence with PCSK9i was 96.1% in the whole period. Median LDL-C levels and % LDL-C reduction attained after 1 year of treatment and in the last follow-up visit were 63 mg/dL (IQR 43-88), 1.6 mmol/L (IQR 1.1-2.23); 61 mg/dL (IQR 44-82), 1.6 mmol/L (IQR 1.1-2.1); 57.6% (IQR 39.5-69); and 58% (IQR 44-68), respectively. 2016 and 2019 ESC/EAS LDL-C goals were attained by 77 and 48% of patients, respectively, at the last follow-up visit (P < 0.001). Mean QoL score increased slightly in the first year and remained stable. CONCLUSION: Long-term persistence with PCSK9i in FH patients is very high, with a good QoL. Effectiveness in LDL-C reduction and LDL-C goal achievement dramatically improved with PCSK9i in this high-risk population in clinical practice setting.

A resilient type of familial hypercholesterolaemia: case-control follow-up of genetically characterized older patients in the SAFEHEART cohort.

AIMS: Knowledge of the features of patients with familial hypercholesterolaemia (FH) who are protected from atherosclerotic cardiovascular disease (ASCVD) is important for the clinical and prognostic care of this apparently high-risk condition. Our aim was to investigate the determinant and characteristics of patients with FH who are protected from ASCVD and have normal life expectancy, so-called 'resilient' FH (R-FH). METHODS AND RESULTS: Spanish Familial Hypercholesterolaemia cohort study (SAFEHEART) is an open, multicentre, nation-wide, long-term prospective cohort study in genetically defined patients with heterozygous FH in Spain. Patients in the registry who at the time of analysis were at least 65 years or those who would have reached that age had they not died from an ASCVD event were analysed as a case-control study. Resilient FH was defined as the presence of a pathogenic mutation causative of FH in a patient aged ≥65 years without clinical ASCVD. Nine hundred and thirty registrants with FH met the study criteria. A defective low-density lipoprotein (LDL)-receptor mutation, higher plasma level of high-density lipoprotein cholesterol (HDL-C), younger age, female gender, absence of hypertension, and lower plasma lipoprotein (a) [Lp(a)] concentration were independently predictive of R-FH. In a second model, higher levels of HDL-C and lower 10-year score in SAFEHEART-RE were also independently predictive of R-FH. CONCLUSION: Resilient FH may be typified as being female and having a defective LDL-receptor mutation, higher levels of plasma HDL-C, lower levels of Lp(a), and an absence of hypertension. The implications of this type of FH for clinical practice guidelines and the value for service design and optional care of FH remains to be established.

INTRODUCCIÓN Y OBJETIVOS: El estudio SAFEHEART se diseñó para analizar la situación y mejorar el conocimiento de la hipercolesterolemia familiar heterocigota (HFH) en España. Nuestro objetivo es determinar la tasa de incidencia de eventos cardiovasculares, el riesgo estimado de sufrir un evento y su modificación, el empleo de tratamiento hipolipemiante y la consecución de objetivos de colesterol unido a lipoproteínas de baja densidad en pacientes con HFH. MÉTODOS: El SAFEHEART es un estudio prospectivo de cohorte, abierto, multicéntrico, de escala nacional, con seguimiento protocolizado a largo plazo en una población de HFH caracterizada molecularmente. Se analizó a los pacientes mayores de 18 años con seguimiento completo. RESULTADOS: El análisis en este estudio se hizo con 2.648 pacientes con HFH. La mediana de seguimiento fue de 6,6 (4,8-9,7) años. La tasa de incidencia general de eventos cardiovasculares fue de 1,3 eventos/100 pacientes-año. El riesgo estimado de sufrir un evento cardiovascular a 10 años se redujo en el seguimiento, y pasó del 1,6 al 1,3% (p <0,001). En el último seguimiento, el 20,6 y el 22,2% de los pacientes en prevención primaria y secundaria consiguieron un colesterol unido a lipoproteínas de baja densidad <100 y <70 mg/dl respectivamente. CONCLUSIONES: En este estudio se muestra la tasa de incidencia de eventos cardiovasculares, el riesgo estimado de sufrir un evento cardiovascular en la mayor población de pacientes con HF en España, así como su modificación, la consecución de objetivos en colesterol unido a lipoproteínas de baja densidad y su tratamiento. Aunque el riesgo cardiovascular de la HFH es elevado, un adecuado tratamiento reduce la probabilidad de sufrir un evento

INTRODUCTION AND OBJECTIVES: The SAFEHEART study was designed to analyze the situation of familial heterozygous hypercholesterolemia (FHH) and improve knowledge of this disease in Spain. Our objective was to determine the incidence rate of cardiovascular events, the estimated risk of developing an event and its modification, the use of lipid-lowering treatment, and the achievement of low-density lipoprotein cholesterol targets in patients with FHH. METHODS: SAFEHEART is a prospective, open, multicenter, nationwide cohort study, with long-term protocol-based follow-up in a population of individuals with molecularly-characterized FHH. We analyzed patients older than 18 years with complete follow-up. RESULTS: We included 2648 patients with FHH. The median follow-up was 6.6 (4.8-9.7) years. The overall incidence rate of cardiovascular events was 1.3 events/100 patient-years. After the follow-up, the 10-year estimated risk of developing a cardiovascular event was reduced from 1.6% to 1.3% (P <.001). In the last follow-up, 20.6% and 22.2% of the patients in primary and secondary prevention achieved low-density lipoprotein cholesterol values <100mg/dL and <70mg/dL, respectively. CONCLUSIONS: This study was performed in the largest population of patients with FHH in Spain. We identified the incidence rate of cardiovascular events, the estimated risk of developing a cardiovascular event and its modification, the achievement of low-density lipoprotein cholesterol targets, and the therapeutic management in this population. Although the cardiovascular risk of FHH is high, appropriate treatment reduces the likelihood of an event

Long-term effect of 2 intensive statin regimens on treatment and incidence of cardiovascular events in familial hypercholesterolemia: The SAFEHEART study.

BACKGROUND: Maximal doses of potent statins are the basement of treatment of familial hypercholesterolemia (FH). Little is known about the use of different statin regimens in FH. OBJECTIVES: The objectives of the study were to describe the treatment changes and low-density lipoprotein cholesterol (LDL-C) goal achievement with atorvastatin (ATV) and rosuvastatin (RV) in the SAFEHEART cohort, as well as to analyze the incidence of atherosclerotic cardiovascular events (ACVEs) and changes in the cardiovascular risk. METHODS: SAFEHEART is a prospective follow-up nationwide cohort study in a molecularly defined FH population. The patients were contacted on a yearly basis to obtain relevant changes in life habits, medication, and ACVEs. RESULTS: A total of 1939 patients were analyzed. Median follow-up was 6.6 years (5-10). The estimated 10-year risk according the SAFEHEART risk equation was 1.61 (0.67-3.39) and 1.22 (0.54-2.93) at enrollment for ATV and RV, respectively (P < .001). There were no significant differences at the follow-up: 1.29 (0.54-2.82) and 1.22 (0.54-2.76) in the ATV and RV groups, respectively (P = .51). Sixteen percent of patients in primary prevention with ATV and 18% with RV achieved an LDL-C <100 mg/dL and 4% in secondary prevention with ATV and 5% with RV achieved an LDL-C <70 mg/dL. The use of ezetimibe was marginally greater in the RV group. One hundred sixty ACVEs occurred during follow-up, being its incidence rate 1.1 events/100 patient-years in the ATV group and 1.2 in the RV group (P = .58). CONCLUSION: ATV and RV are 2 high-potency statins widely used in FH. Although the reduction in LDL-C levels was greater with RV than with ATV, the superiority of RV for reducing ACVEs was not demonstrated.
