경식도 초음파는 심장수술에서 비교적 안전하게 수술 중 심장의 기능 및 수술 결과를 평가할 수 있어 그 이용이 일반화되고 있으며, 경식도 초음파 관련 합병증은 드물지만 하인두 손상이나 식도 천공 등 위험한 합병증이 생길 수 있다. 폐부종을 동반한 심근경색으로 진단받은 77세 남자환자에서 심폐 바이패스를 사용하 않는 관상동맥우회술 시행 후, 수술 중 경식도 초음파 시술과 관련되어 발생한 것으로 추정되는 pyriform sinus 천공 및 이에 동반된 경부 심부감염을 경험하여 보고하는 바이다.

Objective: The community has implemented a variety of exercise programs for the elderly population. However, studies comparing changes in the cardiovascular system through body composition and blood analysis after applying aqua aerobic exercise are insufficient. The purpose of this study was to investigate the effect of a 12 weeks aqua exercise on body composition and cardiovascular index in elderly women. Design: Non-equivalence pre-post design. Methods: Thirty elderly women were assigned to aquarobic group(n=15) and control group(n=15). The aquarobic exercise was 60 minutes per every session, 2times per week, for 12weeks. Weight, skeletal muscle mass, body fat percentage, total cholesterol, triglyceride, HDL cholesterol, and LDL cholesterol were measured before and after the exercise program. Paired and independent t-tests were performed using SPSS program. Results: The result showed was weight(p<0.05), body fat percentage(p<0.05), total cholesterol(p<0.05), triglyceride(p<0.05), HDL cholesterol(p<0.05), and LDL cholesterol(p<0.05) were significantly decreased and skeletal muscle mass(p>0.05) was not significantly increased after aquatic exercise program. Conclusions: According to the study result, aqua exercise program made a positive effect in the improvement of obesity and cardiovascular function in elderly women. Therefore, we suggest that you actively consider implementing the Aquarobic exercise program when operating the community health promotion program in the future. In addition, in future studies, comparative studies according to various ages and genders and studies on the effects of aqua aerobic exercise as a community exercise program for chronically illness patients are needed.

The incidence of annuloaortic ectasia has known rare, and approximately 5-10% of aortic regurgitation. The patient was 44 years old male who complained exertional dyspnea and left anterior chest pain. He had done Lt. side 2 stage thoracoplasty for pulmonary tuberculosis about 20 years ago at Dept.of Chest surgery of National Medical Center. At that time, there was no abnormal findings in cardiovascular system. The preoperative aortic cineangiogram showed pear shaped dilatation [7.3 cm x 6.8 cm] of aortic mot with aortic valve regurgitation but left ventricular ejection function was fair. Preop. ventilatory function test showed mixed type pulmonary insufficiency. Recently, we corrected surgically, by AVR with Carpentier-Edwards Bioprosthesis [29mm] & supracoronary Woven Dacron graft [29mm x 5cm] replacement, with good clinical result for follow up 6 months.

Mid-ventricular obstruction (MVO) rarely occurs in patients without hypertrophic cardiomyopathy. Increased cardiac contractility may play an important role in causing MVO. We experienced a case of severe chest pain and MVO in a 50-year-old female patient. She had hypertension, diabetes, stroke and peripheral artery disease. Her blood pressure was very high (222/122 mmHg) with severe fluctuation. The transthoracic echocardiography revealed MVO accompanied by hyper-dynamic left ventricular systolic function. We regarded her chest pain and MVO as secondary findings related to other diseases. Coronary angiography and several tests for uncontrolled hypertension were performed, and those evaluations revealed that she had coronary artery disease and hyperthyroidism. We considered that the increase in the myocardial oxygen demand in response to the increase in cardiac contractility and workload associated with hyperthyroidism aggravated her symptoms and MVO. She was treated with methimazole and beta blockers and her symptoms dramatically improved.

Cardiomyopathy is an inherited or acquired disease of the myocardium, which can result in severe ventricular dysfunction. Mitochondrial dysfunction is involved in the pathological process of cardiomyopathy. Many dysfunctions in cardiac mitochondria are consequences of mutations in nuclear or mitochondrial DNA followed by alterations in transcriptional regulation, mitochondrial protein function, and mitochondrial dynamics and energetics, presenting with associated multisystem mitochondrial disorders. To ensure correct diagnosis and optimal management of mitochondrial dysfunction in cardiomyopathy caused by multiple pathogenesis, multidisciplinary approaches are required, and to integrate between clinical and basic sciences, ideal translational models are needed. In this review, we will focus on experimental models to provide insights into basic mitochondrial physiology and detailed underlying mechanisms of cardiomyopathy and current mitochondria-targeted therapies for cardiomyopathy.

Background: Patients with high-risk (HR) operable non-small cell lung cancer (NSCLC) may have unique prognostic factors. This study aimed to evaluate surgical outcomes in HR patients and to investigate prognostic factors in HR patients versus standard-risk (SR) patients. Methods: In total, 471 consecutive patients who underwent curative lung resection for NSCLC between January 2012 and December 2017 were identified and reviewed retrospectively. Patients were classified into HR (n=77) and SR (n=394) groups according to the American College of Surgeons Oncology Group criteria (Z4099 trial). Postoperative complications were defined as those of grade 2 or higher by the Clavien-Dindo classification. Results: The HR group comprised more men and older patients, had poorer lung function, and had more comorbidities than the SR group. The patients in the HR group also experienced more postoperative complications (p≤0.001). More HR patients died without disease recurrence. The postoperative complication rate was the only significant prognostic factor in multivariable Cox regression analysis for HR patients but not SR patients. HR patients without postoperative complications had a survival rate similar to that of SR patients. Conclusion: The overall postoperative survival of HR patients with NSCLC was more strongly affected by postoperative complications than by any other prognostic factor. Care should be taken to minimize postoperative complications, especially in HR patients.

Studies of pulmonary function using spirometry were performed before and after pneumonectomy for inflammatory lung diseases from 1985 to 1990 at the Pusan Paik Hospital, Inje Medical College. Fifty-two patients were evaluated ; 33 tuberculosis, 17 bronchiectasis, 2 abscess, and 1 actinomycosis. All patients had preoperative and postoperative FVC, FVC[% predicted], FEV1, %FEV1, MVV and MVV[%predicted] determinations. And above datas were compared each other statistically with applying of the paired t-test. The results were obtained as follows : there were significant decreased after surgery in the values of FVC, FVC[% predicted], MVV, and MVV[% predicted], but the values of FEV1, and %FEV1 were no significant changes after surgery.

연구배경 : 수면 무호흡 증후군의 90% 이상을 차지하는 폐쇄성 수면 무호흡 증후군 환자들은 심혈관계 기능부전이 흔히 동반되며 정상인에 비하여 장기사망률이 증가하는 것으로 알려져 있다. 저자들은 동물실험을 통하여 폐쇄성 무호흡이 심혈관계 기능변화에 미치는 영향을 관찰하고자 하였으며, 또한 수면 무호흡과 관련된 앞으로의 연구에서 적절한 실험동물 모델 설정을 위한 기초자료를 얻고자 하였다. 방 법 : $\alpha$-chloralose로 마취한 16마리의 개를 대상으로 폐쇄성 무호흡을 유발하였고, 무호흡-호흡 주기를 5회 내지 7회 반복하였다. 실내 공기만으로 호흡을 유지시킨 8마리를 산소 비투여군으로 하였고 산소를 투여하면서 호흡을 유지시킨 8마리를 산소 투여군으로 하였다. 무호흡 유발 전 기저상태(기저치), 무호흡 시작 후 25초(무호흡시기), 호흡재개 후 10초(호흡재개 초기)와 25초(호흡재개 후기)에 각각 동맥혈 산소분압과 이산화탄소분압, 심박동수, 심박출량, 대퇴동맥압 및 폐동맥압을 측정하였다. 결 과 : 심박동수는 산소 비투여군에서는 기저치에 비하여 무호흡시기에 유의하게 감소하였고(P<0.01), 시기에 비하여 호흡재개 초기 및 후기에 유의하게 증가하였으며(P<0.01), 산소 투여군에서는 무호흡-호흡 주기에 따른 심박동수 변화가 없었다. 산소투여 여부에 따른 두 군 사이에는 유의한 차이가 있었다. 심박출량은 기저치에 비하여 무호흡시기에 감소하는 경향을 보였으나 통계적 유의성이 없었고, 무호흡시기에 비하여 호흡재개 후기에 유의하게 감소하였으며(P<0.01), 산소투여 여부에 따른 두 군 사이에는 유의한 차이가 없었다. 평균 대퇴동맥압은 기저치에 비하여 무호흡시기에 유의한 감소를 보였고(P<0.05), 산소투여 여부에 따른 두 군 사이에는 유의한 차이가 없었다. 결 론 : 실험동물에서 유발된 폐쇄성 무호흡은 심박동수, 심박출량 및 평균 대퇴동맥압 변화를 초래하였으며, 심박동수 변화는 저산소증과 관련성이 있었다. 본 실험을 통하여 간접적으로 혈역학적 변화에 대한 부분적인 이해가 가능하였으나, 수면 무호흡 증후군 환자에서 동반될 수 있는 심혈관계 기능부전의 병태생리학적 기전을 규명하기 위해서는 자연 수면상태에서 실험할 수 있는 새로운 동물모델의 설정과 더불어 심혈관계 기능변화 및 변화요인에 대한 다양한 연구가 필요하다.
