- Obstructive sleep apnoea is associated with myocardial injury in patients with refractory angina(2016) GEOVANINI, Glaucylara R.; PEREIRA, Alexandre C.; GOWDAK, Luis H. W.; DOURADO, Luciana Oliveira Cascaes; POPPI, Nilson T.; VENTURINI, Gabriela; DRAGER, Luciano F.; LORENZI-FILHO, GeraldoObjective To investigate the association between obstructive sleep apnoea (OSA) severity with markers of overnight myocardial injury in patients with refractory angina. Methods Patients with refractory angina were characterised clinically and they underwent ischaemia imaging stress tests by single-photon emission computed tomography (SPECT) and/or cardiac MRI. The patients were admitted to the hospital, remained under resting conditions for blood determination of high-sensitivity cardiac troponin T (hs-cTnT) at 14:00, 22:00 and after overnight polysomnography at 7:00. Results We studied 80 consecutive patients (age: 62 +/- 10 years; male: 66%; body mass index (BMI): 29.5 +/- 4 kg/m(2)) with well-established diagnosis of refractory angina. The mean apnoea-hypopnoea index (AHI) was 37 +/- 29 events/h and OSA (AHI >15 events/h) was present in 75% of the population. Morning detectable hs-cTnT and above 99th percentile was present in 88% and 36% of the population, respectively. Patients in the first to third quartiles of OSA severity did not have circadian variation of hs-cTnT. In contrast, patients in the fourth quartile (AHI >= 51 events/h) had a circadian variation of hs-cTnT with a morning peak of hs-cTnT that was two times higher than that in the remaining population (p = 0.02). The highest quartile of OSA severity remained associated with the highest quartile of hs-cTnT (p = 0.028) in multivariate analysis. Conclusion Very severe OSA is common and independently associated with overnight myocardial injury in patients with refractory angina.

F.; LORENZI-FILHO, G.- OSA and Depression Are Common and Independently Associated With Refractory Angina in Patients With Coronary Artery Disease(2014) GEOVANINI, Glaucylara R.; GOWDAK, Luis H. W.; PEREIRA, Alexandre C.; DANZI-SOARES, Naury de Jesus; DOURADO, Luciana O. C.; POPPI, Nilson T.; CESAR, Luiz Antonio Machado; DRAGER, Luciano F.; LORENZI-FILHO, GeraldoOBJECTIVE: Refractory angina is a severe form of coronary artery disease (CAD) characterized by persistent angina despite optimal medical therapy. OSA and depression are common in patients with stable CAD and may contribute to a poor prognosis. We hypothesized that OSA and depression are more common and more severe in patients with refractory angina than in patients with stable CAD. METHODS: We used standardized questionnaires and full polysomnography to compare consecutive patients with well-established refractory angina vs consecutive patients with stable CAD evaluated for coronary artery bypass graft surgery. RESULTS: Patients with refractory angina (n = 70) compared with patients with stable CAD (n = 70) were similar in sex distribution (male, 61.5% vs 75.5%; P = .07) and BMI (29.5 +/- 4 kg/m(2) vs 28.5 +/- 4 kg/ m(2), P = .06), and were older (61 +/- 10 y vs 57 +/- 7 y, P = .013), respectively. Patients with refractory angina had significantly more symptoms of daytime sleepiness (Epworth Sleepiness Scale score, 12 +/- 6 vs 8 +/- 5; P < .001), had higher depression symptom scores (Beck Depression Inventory score, 19 +/- 8 vs 10 +/- 8; P < .001) despite greater use of antidepressants, had a higher apnea-hypopnea index (AHI) (AHI, 37 +/- 30 events/h vs 23 +/- 20 events/h; P = .001), higher proportion of oxygen saturation < 90% during sleep (8% + 13 vs 4% + 9, P = .04), and a higher proportion of severe OSA (AHI >= 30 events/h, 48% vs 27%; P = .009) than patients with stable CAD. OSA (P = .017), depression (P < .001), higher Epworth Sleepiness Scale score (P = .007), and lower sleep efficiency (P = .016) were independently associated with refractory angina in multivariate analysis. CONCLUSIONS: OSA and depression are independently associated with refractory angina and may contribute to poor cardiovascular outcome.
- Poor sleep quality and lipid profile in a rural cohort (The Baependi Heart Study)(2019) GEOVANINI, Glaucylara Reis; LORENZI-FILHO, Geraldo; PAULA, Lilian K. de; OLIVEIRA, Camila Maciel; ALVIM, Rafael de Oliveira; BEIJAMINI, Felipe; NEGRAO, Andre Brooking; SCHANTZ, Malcolm von; KNUTSON, Kristen L.; KRIEGER, Jose Eduardo; PEREIRA, Alexandre CostaAim: To test the association between cardiometabolic risk factors and subjective sleep quality assessed by the Pittsburgh sleep quality index (PSQI), independent of obstructive sleep apnea (OSA) and sleep duration. Methods: A total of 573 participants from the Baependi Heart Study, a rural cohort from Brazil, completed sleep questionnaires and underwent polygraphy for OSA evaluation. Multivariable linear regression analysis tested the association between cardiovascular risk factors (outcome variables) and sleep quality measured by PSQI, adjusting for OSA and other potential confounders (age, sex, race, salary/wage, education, marital status, alcohol intake, obesity, smoking, hypertension, and sleep duration). Results: The sample mean age was 43 +/- 16 years, 66% were female, and mean body mass index (BMI) was 26 +/- 5 kg/m(2). Only 20% were classified as obese (BMI >= 30). Overall, 50% of participants reported poor sleep quality as defined by a PSQI score >= 5. A high PSQI score was significantly associated with higher very-low-density lipoprotein (VLDL) cholesterol levels (beta = 0.392, p = 0.012) and higher triglyceride levels (beta = 0.017, p = 0.006), even after adjustments, including the apneaehypopnea index. Further adjustments accounting for marital status, alcohol intake, and medication use did not change these findings. No significant association was observed between PSQI scores and glucose or blood pressure. According to PSQI components, sleep disturbances (beta = 1.976, p = 0.027), sleep medication use (beta = 1.121, p = 0.019), and daytime dysfunction (beta = 1.290, p = 0.024) were significantly associated with higher VLDL serum levels. Only the daytime dysfunction domain of the PSQI components was significantly associated with higher triglyceride levels (beta = 0.066, p = 0.004). Conclusion: Poorer lipid profile was independently associated with poor sleep quality, assessed by the PSQI questionnaire, regardless of a normal sleep duration and accounting for OSA and socio-economic status.

- OSA and Prognosis After Acute Cardiogenic Pulmonary Edema The OSA-CARE Study(2017) UCHOA, Carlos Henrique G.; PEDROSA, Rodrigo P.; JAVAHERI, Shahrokh; GEOVANINI, Glaucylara R.; CARVALHO, Martinha M. B.; TORQUATRO, Ana Claudia S.; LEITE, Ana Paula D. L.; GONZAGA, Carolina C.; BERTOLAMI, Adriana; AMODEO, Celso; PETISCO, Ana Claudia G. P.; BARBOSA, Jose Eduardo M.; MACEDO, Thiago A.; BORTOLOTTO, Luiz A.; OLIVEIRA JR., Mucio Tavares; LORENZI-FILHO, Geraldo; DRAGER, Luciano F.BACKGROUND: Acute cardiogenic pulmonary edema (ACPE) is a life-threatening condition. OSA may be a modifiable risk factor for ACPE recurrence. This study was designed to evaluate the impact of OSA on the incidence of cardiovascular events following ACPE recovery. METHODS: Consecutive patients with confirmed ACPE from 3 centers underwent a sleep study following clinical stabilization. OSA was defined as an apnea-hypopnea index (AHI) >= 15 events/h. The mean follow-up was 1 year, and the primary outcome was ACPE recurrence. RESULTS: A total of 104 patients were included in the final analysis; 61% of the patients had OSA. A higher rate of ACPE recurrence (25 vs 6 episodes; P = .01) and a higher incidence of myocardial infarction (15 vs 0 episodes; P = .0004) were observed in patients with OSA than in those without OSA. All 17 deaths occurred in the OSA group (P = .0001). In a Cox proportional hazards regression analysis, OSA was independently associated with ACPE recurrence (hazard ratio [HR], 3.3 [95% CI, 1.2-8.8]; P = .01), incidence of myocardial infarction (HR, 2.3 [95% CI, 1.1-9.5]; P = .02), cardiovascular death (HR, 5.4 [95% CI, 1.4-48.4]; P = .004), and total death (HR, 6.5 [95% CI, 1.2-64.0]; P = .005). When the analysis was limited only to patients with OSA, levels of AHI and hypoxemic burden and rates of sleep-onset ACPE were significantly higher in those who presented with ACPE recurrence or who died than in those who did not experience these events. CONCLUSIONS: OSA is independently associated with higher rates of ACPE recurrence and both fatal and nonfatal cardiovascular events.
- Atherosclerosis and inflammation: overview and updates(2018) GEOVANINI, Glaucylara Reis; LIBBY, PeterThe concept that inflammation participates pivotally in the pathogenesis of atherosclerosis and its complications has gained considerable attention, but has not yet entered clinical practice. Experimental work has elucidated molecular and cellular pathways of inflammation that promote atherosclerosis. The recognition of atherogenesis as an active process rather than a cholesterol storage disease or a repository of calcium has highlighted some key inflammatory mechanisms. For example, mononuclear phagocytes contribute to all stages of this disease, illustrating the link between inflammation and atherosclerosis. From a clinical perspective, harnessing inflammation may now help target therapeutics, change guidelines, and enter daily practice. Multiple lines of incontrovertible evidence have proven a causal role for low-density lipoprotein (LDL) cholesterol in atherosclerosis, and we have highly effective tools for lowering LDL, consequently reducing events. Yet, even with intense LDL reduction, events still occur. Inflammation can explain some of this residual risk. An anti-inflammatory intervention has now proven capable of improving outcomes in individuals well treated with LDL-lowering agents. A suite of trials are now pursuing anti-inflammatory therapies in this context. Assessment and treatment of residual inflammatory risk are poised to provide new inroads into preventive cardiology. This brief review aims to explore the potential mechanisms underlying the association of inflammation and atherogenesis, and their clinical consequences.
conferenceObject Obstructive sleep apnoea is highly frequent in consecutive patients with refractory angina(2012) GEOVANINI, G.; DRAGER, L.; DOURADO, L. O. C.; POPPI, N. T.; PEREIRA, A. C.; GOWDAK, L. H. W.; LORENZI-FILHO, G.Purpose: Obstructive sleep apnoea (OSA) is common among patients with stable coronary artery disease and may contribute to poor cardiovascular outcome. OSA has not been investigated in patients with refractory angina, a debilitating condition characterized by persistent symptoms despite optimized medical therapy. Methods: Consecutive patients with multi-vessel coronary disease by angiography and refractory angina (severe ischemic symptoms that persist despite optimal medical therapy and whom coronary revascularization procedures are no longer feasible or helpful) were recruited from a specialized out patient clinic. Regardless of sleep complaints, all patients were evaluated by standard overnight polysomnography, symptoms of excessive daytime sleepiness by Epworth Sleepiness Scale (ESS) and one week diary of angina. Results: We evaluated 31 patients (18 males, age: 62±10y, body mass index: 29.8±4.5kg/m2). Co-morbidities were common (dyslipidemia 100%, hypertension 93% and diabetes 61%) and all patients presented persistent angina despite optimal anti-ischemic medical therapy and preserved systolic function (ejection fraction on echocardiography: 53±11%). Patients presented poor sleep quality, poor sleep efficiency (60±16%) and the prevalence of OSA (AHI>15) and severe OSA (AHI>30) was 71 and 55%, respectively. As compared with patients without OSA patients with OSA presented similar age, gender, BMI (28.2±5 vs. 30.4±4.5kg/m2, p=0.26) similar ESS (10±6 vs. 11±6), non-significant trend to higher frequency of diurnal (66 vs. 91%, p=0.13) and nocturnal angina (45 vs. 77%, p=0.10). Conclusions: This preliminary study showed a high frequency of OSA in consecutive patients with refractory angina. Traditional risk factors for OSA, including age, male gender and BMI did not discriminate patients with OSA. Non-significant trends to higher frequency of diurnal and nocturnal angina suggest that OSA may contribute to trigger angina symptoms.
