Background: The incidence of prosthetic tricuspid valve (TV) thrombosis is the highest among heart valves. It can lead to high morbidity and mortality without proper treatment. In this study, we sought to report the management and clinical outcomes of patients with mechanical TV thrombosis.Methods: The current study was conducted in Rajaei Heart Center on 42 patients with mechanical TV thrombosis from 2006 to 2017. The baseline characteristics and the rates of adverse events during the follow-up period were assessed.Results: A total of 67 episodes of mechanical TV thrombosis in 42 patients were observed. The mean age of patients was 45.5 ± 14.3 years (19-77), and overall two-thirds were female. Thrombolytic therapy was used in 41 (61.1%), anticoagulant intensification in 16 (23.9%), and surgery as the first approach in 10 (14.9%) episodes; subsequently, surgery as the final approach was implemented in 20 (29.8%) episodes. In-hospital mortality occurred in two (2.98%) patients. The rates of freedom from recurrent thrombosis were 84%, 61%, and 21% at the end of 1, 4, and 10 years, respectively. Survival rates and freedom from chronic valve dysfunction were 93%, 82%, and 75% after 1, 4, and 10 years.
Conclusions:The results of the present study showed that recurrent thrombosis requiring intervention is a major complication of mechanical TV, which underscores individual-approached therapy and close follow-up.
Background
Hypertension and its consequent end-organ damage including Hypertensive Heart Disease (HHD) are a major concern that impact health, resulting into impairment and reduced quality of life (QOL). The purpose of this study was to describe the burden of HHD in Iran and comparing it with the World Bank upper middle-income countries (UMICs) in terms of disability-adjusted life years (DALY), mortality and prevalence.
Methods
Using data from the Global Burden of Disease study 2017, we compared the number of DALYs, deaths and prevalence trends for HHD from 1990 to 2017 in all age groups for both sex in Iran, and compared the epidemiology and trends with UMICs and globally.
Results
The age-standardized DALY rate for HHD increased by 51.6% for men (95% uncertainty interval [UI] 305.8 to 436.7 per 100,000) and 4.4% for women (95% UI 429.4 to 448.7 per 100,000) in Iran. The age-standardized prevalence of HHD in Iran was almost twice times higher than globally and 1.5-times more than the World Bank UMICs. The age-standardized death rate for HDD increased by 60.1% (95% UI 17.3 to 27.7% per 100,000) for men and by 21.7% (95% UI 25.85 to 31.48 per 100,000) for women from 1990 to 2017. Age-standardized death rate in Iran was 2.4 and 1.9 times higher than globally and UMICs, respectively.
Conclusions
The higher prevalence and death rate in Iran in comparison with UMICs and globally should encourage health care provider to perform intensive screening activities in at risk population to prevent HHD and mitigate its mortality.
Background: Acute coronary syndrome (ACS) is one of the main causes of mortality worldwide. We sought to evaluate the correlation between the severity of coronary artery disease (CAD) and conventional coronary artery risk factors in a large cohort of patients with ACS.
Methods: This study included all patients admitted to the coronary care unit with a diagnosis of ACS between 2003 and 2017. The patients were divided into 2 groups: 1) unstable angina and 2) myocardial infarction. The aims of this study were to evaluate the effects of the risk factors and extension of coronary artery stenosis in patients with ACS according to the Gensini score.
Results: Of a total 40 319 patients who presented with ACS, 18 862 patients (mean age =60.4±11.14 y, male: 67.2%) underwent conventional coronary angiography and met our criteria to enter the final analysis. The median of the Gensini score was 50 (25–88) in the study population. The multivariable analysis showed that age, sex, diabetes mellitus, hypertension, dyslipidemia, family history, cigarette smoking, opium consumption, and myocardial infarction increased the risk of positive Gensini scores. All the aforementioned risk factors, except cigarette smoking and opium consumption, increased the severity of stenosis in those with positive Gensini scores. The strongest relationship was seen vis-à-vis myocardial infarction, sex, and diabetes mellitus.
Conclusion: Our findings suggest that age, sex, diabetes mellitus, dyslipidemia, hypertension, family history, and myocardial infarction have significant effects on the severity of CAD. The obesity paradox in relation to CAD should be taken into consideration and needs further investigation in patients with ACS.
