The purpose the work was studying of cardiovascular system disease prevalence and structure in persons with the inflammatory bowel diseases (IBD) using Gastroenterology department of the Perm regional hospital as an example. It was the retrospective one-stage research including studying case histories of the patients with ulcerative colitis (UC) and Crohn’s disease (CD) examined and treated in gastroenterological clinic for the period of 2013-2016. There were 291 patients with IBD, chronic cardiovascular pathology was revealed only in 90 patients. Comparative analysis showed that combined diseases were mainly spread in men with UC of middle and advanced age. The most typical for them was combination of UC and ischemic heart disease (50% of cases). Cardiovascular system pathology was 1.5 times more common for women with CD pathology. Besides CD, thromboses of peripheral veins (45% of cases) and myocardial dystrophy (24.5% of cases) were the most frequent pathologies. Due to the small number of patients with IBD and cardiovascular system pathology, it is not possible to claim unambiguously the degree of cardiac disorders in patients with IBD. Thus, it is planned to increase the number of observations to reach statistically optimum conclusion. Studying of this problem is of special practical importance for the possibility to regard patients with IBD as a group of patients with high cardiovascular risk. This will necessitate a number of preventive actions to prevent cardiovascular accidents of fatal and non-fatal character.
Inflammatory Bowel Diseases (IBD) including disease Crohn’s (CD) and ulcerative colitis (UC) are the most serious chronic gastrointestinal tract diseases [1-4]. They should be considered as general diseases with multiple immune pathology. Because of this, clinicians are always interested not only in the local changes or complications of IBD associated immediately with an inflammation in the digestive tube but also abenteric or system manifestations of diseases [5-11].
It is well known that in certain cases IBD begin with atypical clinical symptoms, namely with nonspecific abenteric disturbances . This presents certain difficulties in their diagnostics and in some cases delays the time of making the correct diagnosis for several years that negatively affects the forecast of a disease. Besides, abenteric manifestations quite often reduce the general quality of life much more, than typical symptoms in certain IBD phenotypes . The general system complications and abenteric manifestations of IBD are traditionally classified by the pathogenic principle:
Changes occurring due to a system hypersensitization – damage of joints, eyes, skin, oral mucous membrane;
Caused by bacteremia and an antigenemia in the portal system – liver and biliary tract damages;
Relapsing in long-lasting disturbances in the large intestine – anemias, electrolyte disorders [11,13-15].
At the same time, IBD abenteric manifestations are, according to different authors, from 5 to 55%. The majority of large studies show higher prevalence of abenteric manifestations in CD in comparison with UC . At the same time, some works show approximately identical frequency of their occurrence in various types of IBD .
Considering cardiovascular system pathology in persons with IBD, it is one of the most poorly studied disorders today [17,18]. There are only few reports on coronary artery lesions [19,20], development of vascular atherosclerosis and coronary heart disease [9,21,22], dilated cardiomyopathy  and endomyocardial fibrosis , and vascular thromboses [24-28] in IBD patients. The problem is whether patients with IBD can be regarded as persons with high risk of cardiovascular accidents that it is mainly associated with the development of the progressive dysfunction of the vascular endothelium in them [29-33].
However, there is still no consensus on the prevalence of
cardiovascular system diseases in persons with ШИВ, mechanisms
of formation and progressing of endothelial dysfunctions and
thrombophilias in UC and CD, and also there is no answer to a
question: whether it is necessary to taken into account seriously
patients with IBD as a category of patients with high and very high
cardiovascular risk. Since non-infection diseases mortality in the
world is now due to cardiovascular diseases their prevention is an
urgent and significant problem having both in medical, and social
significance. The above arguments made the basis for the present
It was a retrospective study of 291 case histories of patients
with IBD (UC and CD) examined and treated in gastroenterological
clinic of the Perm regional hospital during 2013-2016. According
to life anamnesis written down according to patients report,
results of laboratory and instrumental examination, patients
with the accompanying cardiovascular system pathology,
including hypertension (HP), coronary heart disease (IHD), heart
rhythm disturbances (HRD) and heart conductivity disorders
(HCD), system vasculitis, vascular atherosclerotic lesions,
thromboembolic disorders were selected. Comparison of the
obtained data with literary data on the prevalence of the chosen
cardiovascular diseases in the Russian population in general was
carried out. The results were statistically processed using the
variation statistics method that allowed to present data in the form
of mean values and percent. To evaluate reliability of differences
Wilcoxon nonparametric method for pair comparisons was used,
distinctions were considered reliable at р <0.05.
As a result, in 90(30.93%) of 291 patients with IBD (for the
period of 2013-2106) had chronic cardiovascular system diseases.
They were found in 58 patients with UC (mean age 42.5±14.8
years, 31 men and 27 women) and in 32 patients with CD (mean
age of 35.2±12.1 years, 18 men and 14 women). The structure of
the revealed cardiovascular system diseases in patients with UC is
presented in Figure 1.
Types of heart rhythm disturbance (HRD) in patients of
this group were the following (Figure 2). Types of the heart
conductivity disorders (HCD) in patients with UC were also nonuniform
(Figure 3). The structure of the revealed diseases of
cardiovascular system in persons with CD is presented in Figure 4.
Types of HRD in patients with CD are presented in Figure 5.
The gender analysis in groups with IBD and cardiovascular
pathologies showed that among persons with UC combined
pathology men were twice more affected than women (р =0.032).
At the same time in 50% of cases it was IHD, in 25% - HT, in
20% - myocardial dystrophy and in 5% - HRD and HCD, whereas
women with UC had another structure of cardiac pathology: HT -
in 62% of cases, IHD - in 18.3% of cases, HRD and HCD - in18.7%
of cases, myocardial dystrophy – in 1% oа cases. In patients with
CD cardiovascular diseases were observed 1.5 times more often
in women (р =0.04) than in men. They included thromboses of
peripheral veins in 45% of patients, myocardial dystrophy - in
24.5% of cases, HT - in 6.5% of cases, IHD - in 12.3%, HRD and HCD
– 11.7% of cases. In men of this subgroup: HCD was registered in
80% of cases, HRD - in 14.8%, HT – 5.2% of cases.
Age distribution of patients with IBD and cardiovascular
pathology is presented in Figure 6 & 7. The figure shows that
among patients with UC cardiovascular pathology was mainly
prevalent in older age group (р =0.041). HT, IHD, HRD and
myocardial dystrophy were more common.
According to Figure 7, it is not possible to state the prevailing
age period and incidence of cardiovascular diseases in patients
with CD. At present there are no works devoted to this problem,
moreover due to small number of selected patients with IBD
and cardiovascular system pathology it is not possible to claim
unambiguously the degree of prevalence of cardiac disorders
in patients with IBD. Therefore, it is planned to continue these
studies, increasing the number of observations for receiving
statistically optimum conclusions.
In our opinion, this problem is of practical importance for
separating patients with IBD in the group with high cardiovascular
risk. This will probably necessitate a number of prophylactic
measures to prevent cardiovascular diseases of fatal and non-fatal
character. The received results could be used in real clinical practice of various experts: therapists, gastroenterologists, cardiologists,
general practitioners and vascular surgeons.
a) On the basis of one gastroenterological clinic of the city
of Perm as an example it was shown that in patients with IBD
of middle age the incidence of cardiovascular system chronic
diseases is slightly higher, than in the population of the middle
b) Contrastive analysis showed that predominantly men
with UC of middle and old age suffer from combination of
diseases. The most typical is the combination of UC and
ischemic heart disease (50% of cases).
c) In patients with CD pathology of cardiovascular system
is 1.5 times more common in women than in men. Besides
CD, the most common pathologies include thromboses of
peripheral veins (45% of cases) and myocardial dystrophy
(24.5% of cases).
d) Increasing the group of observation will probably
result in data allowing to define a special category of patients
with IBD for realizing primary preventive measures for
