ABSTRACT

SUMMARY OBJECTIVE: This study aims to evaluate the relationship between periodontal health status and coronary slow flow phenomenon. METHODS: One hundred and two patients who underwent coronary angiography with the diagnosis of stable angina pectoris were included in the study. Patients were divided into two groups: patients with coronary slow flow (Test group) (n=51), and patients with normal coronary angiography (Control group) (n=51). Diagnosis of slow coronary flow was made according to Beltrame criteria by coronary angiography. Demographic characteristics of the participants were recorded. The periodontal health was assessed by clinical periodontal parameters such as probing depth, clinical attachment level, gingival index, plaque index, and bleeding on probing. RESULTS: There were no significant differences between groups as regards the frequencies of hypertension, smoking (p>0.05). As for the periodontal parameters of the study groups, probing depth, gingival index, plaque index, bleeding on probing, and clinical attachment level values were statistically higher in the test group compared to the control group (p<0.05). CONCLUSIONS: Periodontitis might be accepted as one of the underlying causes of coronary slow flow. Patients with coronary slow flow should be evaluated for an underlying periodontal disease, and treatment of periodontal disease can protect against future cardiovascular events.

ABSTRACT

SUMMARY OBJECTIVE Periodontitis may stimulate infectious and immune response and cause the development of atherogenesis, coronary heart disease, and myocardial infarction. The aim of this study was to compare the plateletcrit (PCT) and mean platelet volume (MPV) levels derived from complete blood count (CBC) tests in patients suffering from stage 3 periodontitis with those of healthy individuals without periodontal disease. METHODS The study included 57 patients (28 females and 29 males) with Stage 3 Periodontitis and 57 volunteering individuals (31 females and 26 males) who were periodontally healthy. The age of study participants ranged from 18 to 50 years. Their periodontal condition was investigated with probing depth (PD), clinical attachment level, bleeding on probing, and plaque index. Leukocyte (WBC) and erythrocyte count (RBC), hemoglobin (Hb) and hematocrit (HCT) levels, mean corpuscular volume (MCV) and red cell distribution width (RDW), thrombocyte count, mean platelet volume (MPV), plateletcrit (PCT ), and neutrophil and lymphocyte counts were evaluated based on the CBC test results of the study participants. RESULTS PCT, WBC, Neutrophil, and MPV values were found to be significantly higher in the periodontitis group (p<0.05). There were no significant differences in RBC counts, Hb, HCT, MCV, RDW, and platelet and lymphocyte counts between the two study groups (p>0.05). CONCLUSIONS PCT and MPV levels may be a more useful marker to determine an increased thrombotic state and inflammatory response in periodontal diseases.


RESUMO OBJETIVO A periodontite pode estimular a resposta infecciosa e imunitária e causar o desenvolvimento da aterogênese, doença coronária e infarto do miocárdio. O objetivo deste estudo foi comparar os níveis de plaquetócrito (PCT) e de volume médio de plaquetas (VMP) derivados dos testes de hemograma completo (CBC) em doentes que sofrem de periodontite de fase 3 com os de indivíduos saudáveis, sem doença periodontal. MÉTODOS O estudo incluiu 57 doentes (28 mulheres e 29 homens) com periodontite de fase 3 e 57 voluntários (31 mulheres e 26 homens) que eram periodontalmente saudáveis. A idade dos participantes do estudo variou de 18 a 50 anos. A condição periodontal dos participantes do estudo foi investigada com profundidade de sonda (PD), nível de ligação clínica, hemorragia na sonda e índice de placas. Contagem de leucócitos (WBC) e eritrócitos (RBC), níveis de hemoglobina (Hb) e hematócrito (HCT), volume corpuscular médio (VCM) e largura de distribuição das células vermelhas (RDW), contagem de trombócitos, volume plaquetário médio (MPV), plaquetócrito (PCT) e contagem de neutrófilos e linfócitos foram avaliados com base nos resultados do teste CBC dos participantes do estudo. RESULTADO Verificou-se que os valores de PCT, WBC, neutrófilos e MPV eram significativamente mais elevados no grupo da periodontite (p<0,05). Não houve diferenças significativas nas contagens de glóbulos vermelhos, Hb, HCT, MCV, RDW; nem nas contagens de plaquetas e linfócitos entre os dois grupos estudados (p>0, 05). CONCLUSÃO Os níveis de PCT e MPV podem ser um marcador mais útil para determinar um estado trombótico aumentado e a resposta inflamatória em doenças periodontais.

ABSTRACT

Abstract Background: The risk of cardiovascular events and sudden death increases with type 1 diabetes mellitus (T1DM). Objective: To evaluate electrocardiographic markers of arrhythmias in T1DM patients. Methods: Electrocardiographic parameters reflecting ventricular depolarization and repolarization, namely, QT, QTc, QTd, QTdc, Tp-e, JT, and JTc intervals and Tp-e/QT and Tp-e/QTc ratios, of 46 patients diagnosed with T1DM were retrospectively analyzed and compared with 46 healthy age-, sex-, and body mass-matched controls. Correlations between T1DM duration, hemoglobin A1c (HbA1c), and ventricular repolarization variables were analyzed. P values lower than 0.05 were considered statistically significant. Results: Diabetes duration was 16.6 ± 7.1 years, and HbA1c was 10.81% ± 3.27% in the T1DM group. In comparison with the control group, heart rate, QTc, QTd, QTdc, Tp-e and JTc intervals, Tp-e/QT ratio (p < 0.001), and Tp-e/QTc ratio (p = 0.007) were significantly higher in T1DM patients. T1DM duration and HbA1c levels were significantly correlated with QTc, QTd, QTdc, Tp-e, and JTc intervals and Tp-e/QT and Tp-e/QTc ratios. Conclusions: In T1DM patients, potential electrocardiographic repolarization predictors were significantly increased in correlation with disease duration and HbA1c levels. These findings may contribute to the understanding of sudden cardiac death in patients with T1DM.


Resumo Fundamento: O risco de eventos cardiovasculares e morte súbita aumenta com diabetes mellitus tipo 1 (DM1). Objetivo: Avaliar alguns marcadores eletrocardiográficos de arritmias em pacientes com DM1. Métodos: Parâmetros eletrocardiográficos que refletem despolarização e repolarização ventricular, a saber, os intervalos QT, QTc, QTd, QTdc, Tp-e, JT e JTc e as relações Tp-e/QT e Tp-e/QTc, de 46 pacientes diagnosticados com DM1 foram retrospectivamente analisados e comparados com 46 controles saudáveis, pareados por idade, sexo e massa corporal. As correlações entre duração de DM1, HbA1c e variáveis de repolarização ventricular foram analisadas. Foram considerados estatisticamente significativos os valores de p inferiores a 0,05. Resultados: A duração de diabetes foi de 16,6 ± 7,1 anos, e HbA1c foi 10,81% ± 3,27% no grupo DM1. Em comparação com o grupo controle, a frequência cardíaca, os intervalos QTc, QTd, QTdc, Tp-e e JTc, a relação Tp-e/QT (p < 0,001) e a relação Tp-e/QTc (p = 0,007) foram significativamente mais altos em pacientes com DM1. A duração de DM1 e os níveis de HbA1c foram significativamente correlacionados com os intervalos QTc, QTd, QTdc, Tp-e e JTc e com as relações Tp-e/QT e Tp-e/QTc. Conclusões: Em pacientes com DM1, potenciais preditores eletrocardiográficos de repolarização foram significativamente aumentados em correlação com a duração da doença e com os níveis de HbA1c. Estes achados podem contribuir à compreensão da morte súbita cardíaca em pacientes com DM1.

ABSTRACT

SUMMARY OBJECTIVE To compare the complete blood counts, namely the plateletcrit (PCT) and Platelet-To-Lymphocyte Ratio (PLR) of healthy subjects and those with morbid obesity in the young population. METHODS We included 45 patients with morbid obesity (body mass index -BMI - greater than or equal to 45 kg/m2) and 45 healthy subjects (BMI less than or equal to 25 kg/m2) in our study. Blood samples were obtained from the participants following a 12-hour fasting period. Then we evaluated the levels of hemoglobin (Hb), hematocrit (HCT), red cell distribution width (RDW), mean platelet volume (MPV), white blood cell (WBC), PLR, platelet counts, and PCT in the complete blood count. RESULTS The morbid obesity group had significantly higher platelet counts and PCT values (p<0.001), and PLR values (p=0.033). The value of WBC was also higher in the obese group (p=0.001). MPV was lower in the obesity group but not statistically significant (p=0.815). No significant difference was found between hemoglobin and hematocrit values in these groups; but RDW valuewere higher and statistically significant in the obese group (p=0.001). CONCLUSION PLR or PCT may be more useful as a marker in determining an increased thrombotic state and inflammatory response in morbid obesity.


RESUMO OBJETIVO Comparar as contagens sanguíneas completas, nomeadamente o plateletcrit (PCT) e a razão plaquetas/linfócitos (PPL) de indivíduos saudáveis com aqueles que têm obesidade mórbida na população jovem. MÉTODOS Incluímos 45 pacientes com obesidade mórbida (índice de massa corporal superior a 45 kg/m2) e 45 indivíduos saudáveis (índice de massa corporal inferior a 25 kg/m2) em nosso estudo. Foram obtidas amostras de sangue dos participantes após um período de jejum de 12 horas. Depois, avaliamos os níveis de hemoglobina, hematócrito, largura de distribuição dos glóbulos vermelhos, volume médio de plaquetas, glóbulos brancos, razão plaquetas/linfócitos, contagem de plaquetas e plateletcrit no hemograma completo. RESULTADOS O grupo de obesidade mórbida teve contagens plaquetárias e valores plateletcrit significativamente mais elevados (p<0, 001), e valores razão plaquetas/linfócitos (p=0, 033). O valor dos glóbulos brancos também foi maior no grupo obeso (p=0, 001). O volume médio dos plateletes foi inferior no grupo da obesidade, mas não estatisticamente significativo (p=0, 815). Não foi encontrada diferença significativa entre os valores de hemoglobina e hematócrito nesses grupos, mas os valores da largura de distribuição dos glóbulos vermelhos foram mais elevados no grupo obeso e estatisticamente significativos (p=0, 001). CONCLUSÃO Relação plaquetas-linfócitos e valores de plateletcrit podem ser mais úteis como marcadores na determinação de um estado trombótico aumentado e da resposta inflamatória na obesidade mórbida.

ABSTRACT

Abstract Background: Coronary artery fistula (CAF) is an abnormal connection that links a coronary artery to a cardiac chamber or another major blood vessel. Several studies have shown the association between mean platelet volume (MPV) and cardiovascular diseases. In the literature, there is no previous study about the association between hematologic parameters and congenital CAF. For this reason, we aimed to investigate the association of MPV with CAF. Methods: 70 patients with normal coronary arteries and 50 with coronary artery fistulas were included. Routine blood and biochemical parameters were measured before the arteriography. Differences between groups for continuous variables were analyzed with t- test or Mann-Whitney test. P values < 0.05 were considered significant. Regression analysis was used to find independent predictors of CAF. Results: Baseline patient demographics, including age and clinical risk factors, were similar between the groups. Compared to the control group, median (IQR) High-density lipoprotein cholesterol (HDL) levels were significantly higher (p=0.04) and MPV levels were significantly lower in the CAF group (8.84 ± 1.71fL vs. 10.43 ± 1.34, p < 0.001). In the multivariate analysis, only MPV was a significant predictor of CAF (p < 0.001, 95% CI for OR: 0.438 (0.306-0.629). A negative correlation was found between MPV and fistulae in Pearson's correlation test (r: -0.454, p < 0.001). An MPV level of < 9,6 fL showed sensitivity, specificity, positive predictive value and negative predictive value of 80%, 68%, 71% and 78% respectively (AUC = 0.766, 95% CI, 0.678-0.854) for the prediction of CAF. Conclusion: The present study suggests that MPV may decrease in patients with CAF.


Resumo Fundamento: A fístula da artéria coronária (FAC) é uma conexão anormal que liga a artéria coronária a uma câmara cardíaca ou outro importante vaso sanguíneo. Vários estudos mostraram a associação entre o volume plaquetário médio (VPM) e as doenças cardiovasculares. Na literatura, não há estudo prévio sobre a associação entre os parâmetros hematológicos e a FAC congênita. Por essa razão, nosso objetivo foi investigar a relação do VPM com a FAC. Métodos: Foram incluídos 70 pacientes com artérias coronárias normais e 50 com fístulas de artérias coronárias. Os parâmetros sanguíneos e bioquímicos de rotina foram medidos antes da arteriografia. As diferenças entre os grupos para as variáveis contínuas foram analisadas com o teste t ou teste de Mann-Whitney. Valores de p < 0,05 foram considerados significativos. A análise de regressão foi utilizada para encontrar preditores independentes de FAC. Resultados: Os dados demográficos basais dos pacientes, incluindo idade e fatores de risco clínicos, foram semelhantes entre os grupos. Comparados à mediana do grupo controle (IIQ), os níveis de HDL-colesterol foram significativamente mais altos (p = 0,04) e os níveis de VPM foram significativamente mais baixos no grupo FAC (8,84 ± 1,71fL vs. 10,43 ± 1,34, p < 0,001). Na análise multivariada, apenas o VPM foi um preditor significativo de FAC (p<0,001, IC 95% para OR: 0,438 (0,306-0,629)). Foi encontrada uma correlação negativa entre o VPM e fístulas no teste de correlação de Pearson (r: -0,454, p < 0,001). Um nível de VPM < 9,6 fL apresentou sensibilidade, especificidade, valor preditivo positivo e valor preditivo negativo de 80%, 68%, 71% e 78%, respectivamente (AUC = 0,766, IC 95%, 0,678-0,854) para a previsão de FAC. Conclusão: O presente estudo sugere que o VPM pode diminuir no paciente com FAC.
