Apical hypertrophic cardiomyopathy (AHCM) is a rare form of hypertrophic cardiomyopathy, occasionally resulting in severe complications. The paper covers the etiology and pathogenesis of AHCM, different imaging methods and characteristic appearance of the disease in each of them. Echocardiography and cardiovascular magnetic resonance imaging (CMR) are known to be the most valuable imaging methods. Moreover, this review presents medical and surgical treatment, as well as the clinical course and prognosis. Despite possible morbid events the overall cardiovascular mortality rate of AHCM patients is low, and the prognosis is relatively optimistic.

POLSKIE ARCHIWUM MEDYCYNY WEWNĘTRZNEJ 2016; 126 (5) 330and de le Sierra studies, 3,4 RAH is observed in 10% to 15% of patients treated with antihypertensive drugs.One of the most common causes of RAH is obstructive sleep apnea (OSA). Arterial hypertension is observed in 37% to 56% of patients with OSA, and OSA occurs in 70% to 85% of patients with RAH.2,5 Logan et al 2,6 reported that the prevalence of OSA in patients with RAH is 83% (65% in women and 96% in men). Similar results were IntroductIon In patients with resistant arterial hypertension (RAH), it is impossible to achieve the target values of blood pressure (BP), despite the use of 3 antihypertensive agents (including a diuretic) at maximum doses. Patients with RAH are at high and very high cardiovascular risk, and their treatment constitutes a major clinical and therapeutic challenge.1 The prevalence of RAH is difficult to estimate, and data from clinical studies are often divergent.2 According to the NHANES AbstrActIntroductIon Obstructive sleep apnea (OSA) is considered to be one of the major causes of resistant arterial hypertension (RAH). Apnea episodes cause hypoxia, which triggers the activation of the renin-angiotensin-aldosterone system. This leads to water retention and swelling in the neck region, exacerbating OSA symptoms. It is assumed that the use of eplerenone may reduce the swelling and thus alleviate the severity of OSA.objectIves We aimed to prospectively assess the impact of eplerenone on the severity of OSA and arterial stiffness in patients with RAH. PAtIents And methodsThe study included 31 patients with RAH and OSA. The exclusion criteria were as follows: secondary hypertension, myocardial infarction, stroke 6 months prior to the study, congestive heart failure, chronic kidney failure, alcohol or drug addiction, and active cancer. In all patients, the following tests were performed: blood pressure (BP) measurement (traditionally and using ambulatory BP measuring [ABPM]), applanation tonometry, polysomnography, and the apnea-hypopnea index (AHI) calculation. The tests were done before and after 3 months of eplerenone therapy. Patients received 50 mg of oral eplerenone daily, along with other hypertensive drugs.results The mean age of participants was 57.76 ±6.16 years. After 3 months of eplerenone therapy, we observed a significant reduction in the AHI, neck circumference, BP, aortic pulse wave, and arterial wall stiffness. There were significant correlations between the AHI and mean BP measured by ABPM and between the AHI and arterial stiffness parameters.conclusIons Our results provide evidence for the clinical significance of eplerenone, not only as an antihypertensive medication but also as a drug that may reduce the severity of OSA and arterial stiffness in patients with RAH and OSA.orIGInAl ArtIcle

IntroductionCardiovascular (CV) diseases remain a leading global cause of death. It has been proven that the use of acetylsalicylic acid (ASA) in secondary prevention reduces the CV risk, while the benefits of ASA in primary prevention have recently been debated. The aim of the study was to compare the antiplatelet effect of standardised tomato extract (STE) and ASA in hypertensive patients with high CV risk.Material and methodsThe study involved high-risk patients with arterial hypertension (AH) randomly assigned to one of two groups: group 1 included 33 patients receiving ASA and group 2 included 32 patients receiving STE. The platelet aggregation was determined using the VerifyNow analyser.ResultsAfter 4 weeks of ASA treatment in group 1, a statistically significant reduction in aspirin reaction units (ARU) was observed (p < 0.001). However, the obese subgroup using ASA (n = 18) did not reveal a significant decrease in ARU (p > 0.05). After 4 weeks of STE treatment in the obese subgroup (n = 14), significant declines in ARU by 8.6% (95% CI: –19.5 to –1.7%; p < 0.05) and in P2Y12 reaction units (PRU) by 7.5% (95% CI: –17.6 to 1.8%; p < 0.05) were observed.ConclusionsThe antiplatelet effect of STE in hypertensive patients may be weight dependent. The group with AH and obesity might have potentially benefitted from STE treatment.

The obstructive sleep apnea (OSA) is highly associated with various significant cardiovascular outcomes such as resistant hypertension (RAH). Despite this, as of now the relationship between high night-time blood pressure (BP) and left ventricular hypertrophy (LVH) in patients with OSA and RAH is not fully understood. The aim of this study was to assess the influence of the addition of eplerenone to a standard antihypertensive therapy on parameters of 24-h ambulatory blood pressure measurement (ABPM) as well as on the results of echocardiography and polysomnography in patients with OSA and RAH. The patients were randomly assigned to one of the two study groups: the treatment group, receiving 50 mg/d eplerenone orally for 6 months (n = 51) and the control group, remaining on their standard antihypertensive therapy (n = 51). After that period, a significant reduction in the night-time BP parameters in the treatment group including an increased night blood pressure fall from 4.6 to 8.9% was noted. Additionally, the number of non-dipper patients was reduced by 45.1%. The treatment group also revealed a decrease in left ventricular hypertrophy and in the apnea–hypopnea index (AHI) with a positive correlation being observed between these two parameters. This study is the first to report the improvement of the circadian BP profile and the improvement of the left ventricle geometry in patients with OSA and RAH following the addition of selective mineralocorticoid receptor antagonists to antihypertensive therapy.

Background: Acetylsalicylic acid (ASA) is one of the basic drugs used in the secondary prevention of coronary artery disease (CAD), and in most cases it is taken in the morning in one daily dose. It is suggested that the morning peak of platelet aggregation is responsible for the occurrence of myocardial infarctions and strokes. Hence, the aim of the study was to observe the effect of ASA (morning vs. evening) dosing on the anti-aggregative effect of platelets in patients with CAD and arterial hypertension (AH). Methods: The study involved 175 patients with CAD and AH. Patients were randomly assigned to one of two study groups, taking ASA in the morning or in the evening. The patients had two visits, one baseline and another after 3 months from changing the time of ASA dosage. The platelet aggregation was determined using the VerifyNow analyzer. Results: In the ASA evening group, a significant reduction in platelet aggregation was obtained. In the ASA morning group, a significant difference in response to ASA was observed, depending on sex. In men, the reactivity of platelets decreased, but in women it increased. Conclusions: In the group of patients with CAD and AH, bedtime ASA dosing is associated with a significant reduction in platelet aggregation. The response to ASA may differ between sexes. The benefit gained by changing the drug administration from the morning to the evening is greater in women.
