    <p>This issue of the Brazilian Archives of Cardiology (ABC Cardiol) brings the article &#8220;Women with Polycystic Ovarian Syndrome Exhibit Reduced Baroreflex Sensitivity That May Be Associated with Increased Body Fat&#8221;, by Philbois, SV et al., which draws attention to this clinical condition that is so prevalent in our country and its many aspects related to cardiometabolism, neuroregulation and cardiovascular risk.<xref ref-type="bibr" rid="B1">1</xref>
		</p>
    <p>The Polycystic Ovary Syndrome (PCOS) is the most common endocrine disorder in women of reproductive age,<xref ref-type="bibr" rid="B2">2</xref> with an estimated prevalence of 6 to 10% in this population.<xref ref-type="bibr" rid="B3">3</xref> According to the Rotterdam criteria, PCOS is diagnosed in the presence of at least two of the three criteria: menstrual disorders or amenorrhea with chronic lack of ovulation, clinical and/or biochemical characteristics of hyperandrogenism and the presence of polycystic ovaries on ultrasonography after exclusion of other endocrine disorders.<xref ref-type="bibr" rid="B4">4</xref> Overall, SOP has been considered a reproductive disorder; however, it also represents a significantly increased risk for cardiometabolic disorders.<xref ref-type="bibr" rid="B2">2</xref> The impact on reproduction is predominant during the reproductive years, while cardiometabolic alterations become more important in the later stages of a woman's life.<xref ref-type="bibr" rid="B2">2</xref>
		</p>
    <p>Women with PCOS are at increased risk of obesity, arterial hypertension, glucose intolerance, dyslipidemia and obstructive sleep apnea.<xref ref-type="bibr" rid="B5">5</xref> Obesity is present in approximately 50%,<xref ref-type="bibr" rid="B4">4</xref> whereas insulin resistance occurs in 60% to 95% of them,<xref ref-type="bibr" rid="B6">6</xref> leading to glucose intolerance in 31% to 35%<xref ref-type="bibr" rid="B7">7</xref> and type 2 diabetes mellitus in 7.5% to 20%<sup>8</sup> of these women. However, dyslipidemia is the most common metabolic abnormality in PCOS, generally presenting with the phenotype exhibiting low levels of high-density lipoprotein (HDL) and high levels of triglycerides, consistent with insulin resistance, also presenting with increased insulin resistance and low-density lipoprotein (LDL) cholesterol levels.<xref ref-type="bibr" rid="B7">7</xref><sup>,</sup><xref ref-type="bibr" rid="B8">8</xref>
		</p>
    <p>The prevalence of non-alcoholic fatty liver disease and obstructive sleep apnea are also high in women with PCOS. Even after controlling for body mass index (BMI), women with PCOS are still 30-fold more likely to have sleep-disordered breathing.<xref ref-type="bibr" rid="B9">9</xref><sup>,</sup><xref ref-type="bibr" rid="B10">10</xref>
		</p>
    <p>Sub-clinical markers of cardiovascular disease, such as increased carotid artery intima-media thickness,<xref ref-type="bibr" rid="B11">11</xref> increased calcification of the coronary arteries,<xref ref-type="bibr" rid="B12">12</xref> and higher serum concentrations of C-reactive protein<xref ref-type="bibr" rid="B13">13</xref> have also been associated with PCOS.</p>
    <p>There is evidence that the autonomic nervous system (ANS) plays an important role in ovarian physiology regulation.<xref ref-type="bibr" rid="B14">14</xref> It is estimated that increased sympathetic activity in women with PCOS may be associated with their hormonal and metabolic characteristics.<xref ref-type="bibr" rid="B15">15</xref> Although autonomic dysfunction is considered a predictor of cardiovascular events and mortality,<xref ref-type="bibr" rid="B16">16</xref> there is limited evidence of alterations in this pathophysiological parameter among women with PCOS.</p>
    <p>A study showed that rats with estrogen-induced polycystic ovaries showed high uptake of norepinephrine, and a high degree of the neurotransmitter release with ovarian electrical stimulation.<xref ref-type="bibr" rid="B17">17</xref> Yildirir et al. analyzed heart rate variation (HRV) in women with PCOS, demonstrating a significant increase in the low-frequency spectrum component and a decrease in the high-frequency component in relation to the control group.<xref ref-type="bibr" rid="B18">18</xref> Tekin et al. showed a decrease in heart rate and blood pressure recovery after exertion in comparison to controls.<xref ref-type="bibr" rid="B19">19</xref> Drag et al. demonstrated dysfunction of the sympathetic and parasympathetic components of ANS in women with PCOS using electromyography.<xref ref-type="bibr" rid="B20">20</xref> The authors found no association between weight gain as measured by BMI and alterations in skin sympathetic response tests and R-R interval variation, parameter of the parasympathetic response, attributing to hyperandrogenism and insulin resistance the probable cause of the dysfunction.<xref ref-type="bibr" rid="B20">20</xref> Using the HRV spectral analysis, the study by Philbois SV et al., published in this issue of ABC Cardiol, found no alterations in autonomic cardiovascular control in women with PCOS.<xref ref-type="bibr" rid="B1">1</xref> However, the authors correlated the decline in baroreflex sensitivity, an important measure of autonomic cardiovascular function, as well as the attenuation of HRV values, with the increase of body fat in women with PCOS.<xref ref-type="bibr" rid="B1">1</xref>
		</p>
    <p>Although the results of the studies are conflicting, it can be concluded that insulin resistance, hyperandrogenism and obesity may result in autonomic dysfunction in PCOS.<xref ref-type="bibr" rid="B1">1</xref><sup>,</sup><xref ref-type="bibr" rid="B17">17</xref><sup>-</sup><xref ref-type="bibr" rid="B21">21</xref> This autonomic dysregulation is recognized as a factor of worse prognosis,<xref ref-type="bibr" rid="B16">16</xref><sup>,</sup><xref ref-type="bibr" rid="B22">22</xref> in addition to the set of metabolic<xref ref-type="bibr" rid="B5">5</xref><sup>-</sup><xref ref-type="bibr" rid="B8">8</xref> clinical,<xref ref-type="bibr" rid="B9">9</xref><sup>,</sup><xref ref-type="bibr" rid="B10">10</xref> and structural alterations<xref ref-type="bibr" rid="B11">11</xref><sup>-</sup><xref ref-type="bibr" rid="B13">13</xref> related to the syndrome when determining a higher cardiovascular risk. Despite all these demonstrations of subclinical dysfunction, there is still a lack of conclusive, long-term follow-up studies in these women, aiming to demonstrate definitive evidence of increased cardiovascular clinical outcomes associated with PCOS.<xref ref-type="bibr" rid="B23">23</xref>.</p>

      <p>Um estudo demonstrou que ratos com ov&#225;rios polic&#237;sticos induzidos por estrog&#234;nio tiveram uma alta capta&#231;&#227;o de norepinefrina, e um alto grau de libera&#231;&#227;o do neurotransmissor com a estimula&#231;&#227;o el&#233;trica ovariana.<xref ref-type="bibr" rid="B17">17</xref> Yildirir et al. analisaram as varia&#231;&#245;es da frequ&#234;ncia card&#237;aca (VFC) em mulheres com SOP demonstrando um aumento significativo no componente de baixa frequ&#234;ncia do espectro e uma diminui&#231;&#227;o no componente de alta frequ&#234;ncia em rela&#231;&#227;o ao grupo controle.<xref ref-type="bibr" rid="B18">18</xref> Tekin et al. mostraram uma diminui&#231;&#227;o na recupera&#231;&#227;o da frequ&#234;ncia card&#237;aca e da press&#227;o arterial ap&#243;s esfor&#231;o em compara&#231;&#227;o com controles.<xref ref-type="bibr" rid="B19">19</xref> Drag et al. demonstraram disfun&#231;&#227;o dos componentes simp&#225;tico e parassimp&#225;tico do SNA em mulheres com SOP utilizando eletromiografia.<xref ref-type="bibr" rid="B20">20</xref> Os autores n&#227;o encontraram associa&#231;&#227;o entre o aumento de peso, avaliado pelo IMC, e as altera&#231;&#245;es nos testes de resposta simp&#225;tica da pele e a varia&#231;&#227;o do intervalo R-R, par&#226;metro da resposta parassimp&#225;tica, atribuindo ao hiperandrogenismo e &#224; resist&#234;ncia &#224; insulina a prov&#225;vel causa da disfun&#231;&#227;o.<xref ref-type="bibr" rid="B20">20</xref> Utilizando a an&#225;lise espectral da VFC, o estudo de Philbois SV et al., publicado neste n&#250;mero dos ABC Cardiol, n&#227;o encontrou altera&#231;&#245;es no controle auton&#244;mico cardiovascular em mulheres com SOP.<xref ref-type="bibr" rid="B1">1</xref> Contudo, os autores correlacionam a dimuni&#231;&#227;o da sensibilidade do barorreflexo, uma importante medida da fun&#231;&#227;o autono&#770;mica cardiovascular, assim como a atenua&#231;&#227;o dos valores da VFC, com o aumento da gordura corporal em mulheres com SOP.<xref ref-type="bibr" rid="B1">1</xref>

      <p>Embora os resultados dos estudos sejam conflitantes, conclui-se que a resist&#234;ncia &#224; insulina, o hiperandrogenismo e a obesidade possam resultar em disfun&#231;&#227;o auton&#244;mica na SOP.<xref ref-type="bibr" rid="B1">1</xref><sup>,</sup><xref ref-type="bibr" rid="B17">17</xref><sup>-</sup><xref ref-type="bibr" rid="B21">21</xref> Essa desregula&#231;&#227;o auton&#244;mica &#233; reconhecida como fator de pior progn&#243;stico,<xref ref-type="bibr" rid="B16">16</xref><sup>,</sup><xref ref-type="bibr" rid="B22">22</xref> podendo se somar &#224; pl&#234;iade de altera&#231;&#245;es metab&#243;licas,<xref ref-type="bibr" rid="B5">5</xref><sup>-</sup><xref ref-type="bibr" rid="B8">8</xref> cl&#237;nicas<xref ref-type="bibr" rid="B9">9</xref><sup>,</sup><xref ref-type="bibr" rid="B10">10</xref> e estruturais<xref ref-type="bibr" rid="B11">11</xref><sup>-</sup><xref ref-type="bibr" rid="B13">13</xref> relacionadas &#224; s&#237;ndrome na determina&#231;&#227;o de um maior risco cardiovascular.
