Guidelines and recommendations should help the health professionals to make decisions in their daily practice. However, the final decisions concerning an individual patient must be made by the responsible health professional(s) in consultation with the patient and caregiver as appropriate.\n\nA great number of Guidelines have been issued in recent years by the European Society of Cardiology (ESC) as well as by other societies and organisations. Because of the impact on clinical practice, quality criteria for the development of guidelines have been established in order to make all decisions transparent to the user. The recommendations for formulating and issuing ESC Guidelines can be found on the ESC website (http://www.escardio.org/guidelines-surveys/esc-guidelines/about/Pages/rules-writing.aspx). ESC Guidelines represent the official position of the ESC on a given topic and are regularly updated.\n\nMembers of this Task Force were selected by the ESC to represent professionals involved with the medical care of patients with this pathology. Selected experts in the field undertook a comprehensive review of the published evidence for management (including diagnosis, treatment, prevention and rehabilitation) of a given condition according to ESC Committee for Practice Guidelines (CPG) policy. A critical evaluation of diagnostic and therapeutic procedures was performed including assessment of the risk-benefit-ratio. Estimates of expected health outcomes for larger populations were included, where data exist. The level of evidence and the strength of recommendation of particular management options were weighed and graded according to predefined scales, as outlined in Tables 1 and 2 .\n\nThe experts of …

2014 ESC Guidelines on diagnosis and management of hypertrophic cardiomyopathy The Task Force for the Diagnosis and Management of Hypertrophic Cardiomyopathy of the European Society of Cardiology (ESC)

Report of the 1995 World Health Organization/International Society and Federation of Cardiology Task Force on the Definition and Classification of cardiomyopathies.

ContextThroughout the past 40 years, a vast and sometimes contradictory literature
has accumulated regarding hypertrophic cardiomyopathy (HCM), a genetic cardiac
disease caused by a variety of mutations in genes encoding sarcomeric proteins
and characterized by a broad and expanding clinical spectrum.ObjectivesTo clarify and summarize the relevant clinical issues and to profile
rapidly evolving concepts regarding HCM.Data SourcesSystematic analysis of the relevant HCM literature, accessed through
MEDLINE (1966-2000), bibliographies, and interactions with investigators.Study Selection and Data ExtractionDiverse information was assimilated into a rigorous and objective contemporary
description of HCM, affording greatest weight to prospective, controlled,
and evidence-based studies.Data SynthesisHypertrophic cardiomyopathy is a relatively common genetic cardiac disease
(1:500 in the general population) that is heterogeneous with respect to disease-causing
mutations, presentation, prognosis, and treatment strategies. Visibility attached
to HCM relates largely to its recognition as the most common cause of sudden
death in the young (including competitive athletes). Clinical diagnosis is
by 2-dimensional echocardiographic identification of otherwise unexplained
left ventricular wall thickening in the presence of a nondilated cavity. Overall,
HCM confers an annual mortality rate of about 1% and in most patients is compatible
with little or no disability and normal life expectancy. Subsets with higher
mortality or morbidity are linked to the complications of sudden death, progressive
heart failure, and atrial fibrillation with embolic stroke. Treatment strategies
depend on appropriate patient selection, including drug treatment for exertional
dyspnea (β-blockers, verapamil, disopyramide) and the septal myotomy-myectomy
operation, which is the standard of care for severe refractory symptoms associated
with marked outflow obstruction; alcohol septal ablation and pacing are alternatives
to surgery for selected patients. High-risk patients may be treated effectively
for sudden death prevention with the implantable cardioverter-defibrillator.ConclusionsSubstantial understanding has evolved regarding the epidemiology and
clinical course of HCM, as well as novel treatment strategies that may alter
its natural history. An appreciation that HCM, although an important cause
of death and disability at all ages, does not invariably convey ominous prognosis
and is compatible with normal longevity should dictate a large measure of
reassurance for many patients.

2011 ACCF/AHA guideline for the diagnosis and treatment of hypertrophic cardiomyopathy: a report of the American College of Cardiology Foundation/American Heart Association Task Force on Practice Guidelines.

Background Hypertrophic cardiomyopathy (HCM) is a genetically transmitted disease and an important cause of morbidity and sudden cardiac death in young people, including competitive athletes. At present, however, few data exist to estimate the prevalence of this disease in large populations. Methods and Results As part of the Coronary Artery Risk Development in (Young) Adults (CARDIA) Study, an epidemiological study of coronary risk factors, 4111 men and women 23 to 35 years of age selected from the general population of four urban centers had technically satisfactory echocardiographic studies during 1987 through 1988. Probable or definite echocardiographic evidence of HCM was present in 7 subjects (0.17%) on the basis of identification of a hypertrophied, nondilated left ventricle and maximal wall thickness ≥15 mm that were not associated with systemic hypertension. Prevalence in men and women was 0.26:0.09%; in blacks and whites, 0.24:0.10%. Ventricular septal thickness was 15 to 21 mm (mean, 17 mm) in ...
