The role of a gender effect (that means differences in clinical manifestations, access to therapies and response to treatments according to gender) in cardiomyopathies remains a matter of debate. Although recent studies have evaluated the differences in the clinical features and prognosis between the two sexes, many issues remain to be elucidated. At present, the only sex-specific condition that affects females is peripartum cardiomyopathy. ⋯ Conversely, women who are symptomatic before pregnancy or have severe hypertrophy with important outflow tract gradient are at higher risk and should be referred to a tertiary center to be evaluated on a case by case basis. Pregnancy in women with dilated cardiomyopathy and significant left ventricular systolic dysfunction represents a high-risk condition. In addition, information on the clinical course and potential complications in pregnant women with arrhythmogenic right ventricular cardiomyopathy or restrictive cardiomyopathy is limited to individual reports.

Comparative Study[Female gender and pulmonary arterial hypertension: a complex relationship].
Pulmonary arterial hypertension (PAH) is a severe clinical condition defined as mean pulmonary artery pressure ≥25 mmHg and normal pulmonary capillary wedge pressure (≤15 mmHg). In PAH the increase in pulmonary pressure is due to an intrinsic disease of the small pulmonary arteries (resistance vessels) characterized by vascular proliferation and remodeling. The increase in pulmonary vascular resistance with subsequent elevation of the right ventricular afterload leads to right ventricular failure after variable periods of time. ⋯ As such, the current clinical recommendation is that pregnancy should strongly be discouraged and if it occurs, early termination is advised. When PAH is not diagnosed until late in pregnancy, close follow-up of the mother is mandatory and elective planned delivery is recommended: care of pregnant women with PAH requires a highly planned, multidisciplinary approach, involving obstetricians, pulmonary hypertension specialists, anesthesiologists and intensivists, preferably in a dedicated PAH referral center. Use of female hormones for birth control and postmenopausal replacement therapy in PAH patients still remains controversial; in fact, although it has been suspected to be a trigger factor for PAH development, a formal association based on case-control studies has not been documented.

Although the incidence of sudden cardiac death (SCD) is greater in men than in women, it represents an important mode of death also in the female gender. Sex-related differences have been identified not only in the prevalence of the phenomenon, but also in risk factors and etiology of SCD. The peripartum period represents a peculiar trigger of SCD in women with underlying cardiovascular substrates. ⋯ While the incidence of SCD increases progressively with age in adult elderly women to reach a 1:1 male:female ratio after the age of 80 years, mostly due to the increasing incidence of atherosclerotic disease in the postmenopausal period, SCD in young women is a rare event and usually associated with non-atherosclerotic disease, such as mitral valve prolapse, spontaneous coronary dissection, myocarditis, inherited cardiomyopathies and congenital heart diseases. The heart can be found structurally normal and inherited ion channel diseases are often implicated. Gender differences in the risk of SCD deserve further attention, since they affect the evaluation of interventions designed to reduce the rate of female SCD.
