ABSTRACT. The rupture of the left ventricle free wall is one of the most dangerous complications of myocardial infarction. Due to the widespread availability of echocardiography method, the detection of this fatal complication and the number of lives saved after surgery grew. The survival of patients depends on early diagnosis, stabilization of the patient’s condition, promptness and tactics of surgical intervention. We report a case of successful closure of a rupture of the left ventricle free wall on the 15th day after myocardial infarction.РЕЗЮМЕ. Разрыв свободной стенки левого желудочка (ЛЖ) является одним из наиболее опасных осложнений инфаркта миокарда. Благодаря широкому распространению и доступности метода эхо-кардиографии, увеличилось число диагностированных случаев прижизненного выявления этого фатального осложнения и количество спасенных жизней после хирургической коррекции. Выживание больных зависит от ранней диагностики, стабилизации состояния больного, оперативности и тактики хирургического вмешательства. Мы приводим случай успешного ушивания разрыва свободной стенки ЛЖ на 15-е сутки от острого инфаркта миокарда

Ранние результаты после шунтирования коронарных артерий у пациентов с выраженной ишемической дисфункцией левого желудочка

Introduction. The number of patients with severe ischemic left ventricular dysfunction (ILVD), who undergo coronary artery bypass, increasing each year. ILVD is an established risk factor for mortality in patients after myocardial revascularization during the early and late postoperative periods.Aim of study. To evaluate the early results of surgical myocardial revascularization in patients with coronary artery disease (CAD) and severe ILVD.Material and methods. The study included 149 patients with coronary artery disease with severe left ventricular dysfunction (ejection fraction (EF) ≤39%), operated from January 2002 to December 2018. different variables were assessed (pre- and postoperative), including LV ejection fraction and end systolic volume index (ESVI).Results. The average age of the patients was 59.36±8.97 years (from 30 to 78 years), 93% of the patients were men. In 28 patients (19%), ILVD developed against the background of myocardial infarction (MI) and in 121 (81%) due to ischemic cardiomyopathy (ICMP) with a history of myocardial infarction. The mean EF before surgery was 36.64±3.17 (from 21 to 39%). In the postoperative period, there was an increase in EF, which averaged 44.92±4.92 (from 36 to 59%) (p value <0.001). The mean LV ESVI before surgery was 60.23±11.52 ml/m2. In the immediate postoperative period ESVI decreased to 46.26±12.40 ml/m2 (the value of p<0.001). The average number of bypass coronary arteries in one patient was 3.9±0.87. There was also a decrease in the degree of mitral regurgitation in most patients after coronary artery bypass grafting (CABG) (p value <0.001). Hospital mortality was 2% (3 patients).Conclusion. Coronary artery bypass grafting in patients with severe ischemic left ventricular dysfunction can be performed with low mortality. Surgical myocardial revascularization can be considered a safe and effective operation for patients with coronary artery disease with a satisfactory condition of the distal coronary arteries, low ejection fraction, and with a predominance of viable myocardium.Введение. Количество пациентов с тяжелой ишемической левожелудочковой дисфункцией (ИЛЖД), которым выполняют шунтирование коронарных артерий, увеличивается из года в год. ИЛЖД является установленным фактором риска смертельных исходов у больных после реваскуляризации миокарда в раннем и отдаленном послеоперационном периодах.Цель исследования. Оценить ранние результаты хирургической реваскуляризации миокарда у больных ишемической болезнью сердца (ИБС) и выраженной ИЛЖД.Материал и методы. В исследования включены 149 больных ИБС с тяжелым нарушением функции левого желудочка — ЛЖ (фракция выброса (ФВ) ≤39%), оперированных с января 2002 г. по декабрь 2018 г. Были оценены различные переменные величины (предоперационные и послеоперационные), включая такие, как ФВ ЛЖ и индекс конечно систолического объема (ИКСО).Результаты. Средний возраст пациентов составил 59,36±8,97 года (от 30 до 78 лет), 93% пациентов были мужчинами. У 28 пациентов (19%) ИЛЖД развилась на фоне острого инфаркта миокарда (ОИМ) и у 121 (81%) — вследствие ишемической кардиомиопатии (ИКМП) с перенесенным инфарктом миокарда в анамнезе. Среднее значение ФВ ЛЖ перед операцией составило 36,64±3,17 (от 21 до 39%). В послеоперационном периоде отмечалось увеличение ФВ ЛЖ, которое составило в среднем 44,92±4,92 (от 36 до 59%) (значение р<0,001). Среднее значение ИКСО ЛЖ до операции составило 60,23±11,52 мл/м2. В ближайшем послеоперационном периоде отмечено снижение ИКСО до 46,26±12,40 мл/м2 (значение р<0,001). Среднее количество шунтированных коронарных артерий у одного пациента составило 3,9±0,87. Наблюдалось также уменьшение степени митральной регургитации у большинства больных после коронарного шунтирования (КШ) (значение р<0,001). Госпитальная летальность составила 2% (3 пациента).Выводы. Коронарное шунтирование у пациентов с тяжелой формой ишемической левожелудочковой дисфункции может быть выполнено с низкой летальностью. Хирургическую реваскуляризацию миокарда можно считать безопасной и эффективной операцией для пациентов с ишемической болезнью сердца с удовлетворительным состоянием дистальных отделов коронарных артерий, низкой фракцией выброса и с преобладанием жизнеспособного миокарда

Успешное хирургическое лечение гигантской истинной аневризмы левого желудочка (клиническое наблюдение)

We report the successful surgical treatment of a giant true thrombosed aneurysm of the left ventricle.A 59-year-old male patient Z. was admitted with severe heart failure and chronic thrombosed aneurysm of the left ventricle, formed after acute extensive myocardial infarction, despite successful installation of a stent into the anterior descending artery in the acute period. Echocardiography revealed a significant increase in the volume of the left ventricular cavity, a significant decrease in the contractile function of the left ventricular myocardium (ejection fraction 32-36%), a giant left ventricular aneurysm (9x6 cm) with a parietal lining thrombus in the aneurysm cavity. Coronary angiography showed an aneurysmal dilatation of the circumflex branch of more than 6 mm, hemodynamically significant stenosis of two coronary arteries. According to the scintigraphy, the myocardium beyond the scar tissue was viable. The patient underwent resection of a left ventricular aneurysm, endoventricular plasty (Dor procedure), coronary artery bypass surgery of the circumflex artery and obtuse marginal branch of the left coronary artery.The patient was discharged in satisfactory condition on day 14 after surgery. At follow-up 6 months after surgery, an increase in the ejection fraction to 3941% was noted.В настоящем сообщении приведено наблюдение успешного хирургического лечения гигантской истинной тромбированной аневризмы левого желудочка (ЛЖ). Больной З., 59 лет, поступил в отделение с выраженной сердечной недостаточностью и  хронической  тромбированной аневризмой ЛЖ, сформировавшейся после перенесенного острого обширного инфаркта миокарда, несмотря на проведенное успешное стентирование инфарктзависимой передней нисходящей артерии в остром периоде. По данным эхокардиографии выявлено значительное увеличение объема полости ЛЖ, значительное снижение сократительной функции миокарда ЛЖ (фракция выброса 32–36%), гигантская аневризма ЛЖ (9x6 см) с пристеночным выстилающим тромбом в полости аневризмы. По результатам коронароангиографии выявлено аневризматическое расширение огибающей ветви (ОВ) более 6 мм, гемодинамически значимое стенотическое поражение двух коронарных артерий. По данным сцинтиграфии, миокард вне зоны рубцовой ткани был жизнеспособен. Больному выполнена операция: резекция аневризмы ЛЖ, эндовентрикулопластика по Дору, аортокоронарное шунтирование ОВ и ветви тупого края левой коронарной артерии. Пациент выписан в удовлетворительном состоянии на 14-е сут после операции. При контрольном обследовании через 6 мес после операции было отмечено возрастание фракции выброса до 39–41%

Potentially fatal new trend in performance enhancement: a cautionary note on nitrite

BACKGROUND: Considerable interest has been shown by athletes and scientists in the potential for nitric oxide and associated vasodilators to enhance performance. This study aims to explore potential misuse of vasodilators by the athletes, and to highlight the growing concern over these agents. METHODS: Retrospective analyses of anonymous inquiries recorded in the Drug Information Database (DID) between January 2006 and June 2008 (inclusive). In this 30-month period, the DID recorded 198,023 inquiries, of which 118,724 were UK Licensed Pharmaceutical products with a further 79,299 inquiries made for substance not found in the database. RESULTS: Phosphodiesterase type 5 (PDE-5) inhibitors, dominated by Viagra(R), ranked 16th among the substance groups. The proportion of the inquiries made regarding PDE-5 inhibitors, especially in comparison to antibiotics, painkillers or alcohol, appears to be above the level that would normally be expected from medical need. No significant change in the months leading up to the Beijing Olympics was observed. On the contrary, the Nitric/Nitrate group showed a notable increase between 2006-2007 and 2008, suggesting a potential increase in interest in using nitric oxide among athletes. CONCLUSIONS: With patents recently filed for the use of agents containing sodium nitrite/nitrate to enhance blood flow for performance enhancement in sport, coupled with anecdotal evidence from internet athlete forums and media, there is a concern that athletes may endanger their health by using vasodilators to enhance athletic performance. PDE-5 inhibitors or chemicals in the nitrate/nitrate group are currently not prohibited or tested for by the doping control agencies but some are highly dangerous to health and can lead to cardiovascular collapse, coma and death. Its promotion among athletes as a performance enhancing supplement is ethically and medically questionable

Performance enhancement with supplements: incongruence between rationale and practice.

<p>Abstract</p> <p>Background</p> <p>Athletes are expected to consider multiple factors when making informed decision about nutritional supplement use. Besides rules, regulations and potential health hazards, the efficacy of different nutritional supplements in performance enhancement is a key issue. The aim of this paper was to find evidence for informed decision making by investigating the relationship between specific performance-related reasons for supplement use and the reported use of nutritional supplements.</p> <p>Methods</p> <p>The 'UK Sport 2005 Drug Free Survey' data (n = 874) were re-analysed using association [χ²] and 'strength of association' tests [ϕ] to show the proportion of informed choices and to unveil incongruencies between self-reported supplement use and the underlying motives.</p> <p>Results</p> <p>Participants (n = 520) reported supplement use in the pattern of: vitamin C (70.4%), creatine (36.1%), whey protein (30.6%), iron (29.8%), caffeine (23.8%), and ginseng (8.3%) for the following reasons: strength maintenance (38.1%), doctors' advice (24.2%), enhancing endurance (20.0%), ability to train longer (13.3%), and provided by the governing body (3.8%). Of thirty possible associations between the above supplements and reasons, 11 were predictable from literature precedents and only 8 were evidenced and these were not strong (ϕ < .7). The best associations were for the ability to train longer with creatine (reported by 73.9%, χ²= 49.14, p < .001; ϕ = .307, p < .001), and maintaining strength with creatine (reported by 62.6%, χ²= 97.08, p < .001; ϕ = .432, p < .001) and whey protein (reported by 56.1%, χ²= 97.82, p < .001; ϕ = .434, p < .001).</p> <p>Conclusion</p> <p>This study provided a platform for assessing congruence between athletes' reasons for supplement use and their actual use. These results suggest that a lack of understanding exists in supplement use. There is an urgent need to provide accurate information which will help athletes make informed choices about the use of supplements.</p
