Arterial Stiffness Changes in Adult Cancer Patients Receiving Anticancer Chemotherapy: A Real-World Bicentric Experience.

Background Chemotherapy correlates to acute and long-term cardiotoxicity, is reflected clinically by myocardial and vascular endothelial dysfunction, and can cause cardiovascular complications. Thus, early diagnosis of cardiovascular disease in cancer patients undergoing anti-cancer treatment is necessary to enhance long-term survival. Our principal objective in this study was to discern the impact of specific anti-cancer chemotherapeutics and biologics on arterial stiffness alterations before and after the administration. Methods Conducted at Mustafa Bacha University Hospital, Algeria, the study focused on arterial stiffness in anti-cancer chemotherapy patients. Assessments included blood pressure, diabetes, and dyslipidemia, with precise measurements using validated systems, particularly pulse wave velocity (PWV). Various chemotherapy protocols were applied, and statistical analysis with R software (R Foundation for Statistical Computing, Vienna, Austria) maintained a significance level of p=0.05. Key outcomes centered on carotid-femoral PWV and secondary endpoints such as central and peripheral pressures and pulse pressure (PP). Univariate and bivariate analyses were conducted using appropriate statistical tests.  Results A comparative prospective observational study was completed on 58 patients (34 women and 24 men; mean age: 52.64 +/- 12.12 years) treated with anti-cancer chemotherapy agents. Our evaluation included a complete clinical exam, electrocardiogram, Doppler echocardiography, and applanation tonometry with arterial stiffness measurement using PWV. Patients presented significantly higher levels of carotid-femoral PWV, regardless of the chosen chemotherapy protocol, with no return to the initial level after one year of stopping treatment (p-value < 0.01). Moreover, this increase was more significant in patients with diabetes and hypertension and patients treated with monoclonal antibodies or intercalants.  Conclusion This prospective study shows that chemotherapy patients have elevated arterial stiffness, emphasizing the need to assess PWV and monitor cardiovascular risk factors. PP measurement with PWV could improve risk management.

[Anomalous origin of right coronary artery from pulmonary artery associated to left main coronary stenosis]. / Anomalie de connexion de l'artère coronaire droite au niveau de l'artère pulmonaire associée à une sténose du tronc commun gauche.

We describe herein a case of a 16 years-old female patient referred to our department for further exploration of a chest pain. Color Doppler echocardiography revealed an abnormal flow at the level of the pulmonary artery. Exercise testing was abnormal leading to further imaging including computed cardiac tomography followed by coronary angiography which showed anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA) associated with mid shaft left main stenosis. We discuss this uncommon association and therapeutic options.

Clinical features, socioeconomic status, management, short and long-term outcomes of patients with acute myocardial infarction: Phase I results of PEACE MENA registry.

BACKGROUND: The Program for the Evaluation and Management of Cardiac Events in the Middle East and North Africa (PEACE MENA) is a prospective registry program in Arabian countries that involves in patients with acute myocardial infarction (AMI) or acute heart failure (AHF). METHODS: This prospective, multi-center, multi-country study is the first report of the baseline characteristics and outcomes of inpatients with AMI who were enrolled during the first 14-month recruitment phase. We report the clinical characteristics, socioeconomic, educational levels, and management, in-hospital, one month and one-year outcomes. RESULTS: Between April 2019 and June 2020, 1377 patients with AMI were enrolled (79.1% males) from 16 Arabian countries. The mean age (± SD) was 58 ± 12 years. Almost half of the population had a net income < $500/month, and 40% had limited education. Nearly half of the cohort had a history of diabetes mellitus, hypertension, or hypercholesterolemia; 53% had STEMI, and almost half (49.7%) underwent a primary percutaneous intervention (PCI) (lowest 4.5% and highest 100%). Thrombolytics were used by 36.2%. (Lowest 6.45% and highest (90.9%). No reperfusion occurred in 13.8% of patients (lowest was 0% and highest 72.7%).Primary PCI was performed less frequently in the lower income group vs. high income group (26.3% vs. 54.7%; P<0.001). Recurrent ischemia occurred more frequently in the low-income group (10.9% vs. 7%; P = 0.018). Re-admission occurred in 9% at 1 month and 30% at 1 year, whereas 1-month mortality was 0.7% and 1-year mortality 4.7%. CONCLUSION: In the MENA region, patients with AMI present at a young age and have a high burden of cardiac risk factors. Most of the patients in the registry have a low income and low educational status. There is heterogeneity among key performance indicators of AMI management among various Arabian countries.

Clinical Features, Socioeconomic Status, Management, and Outcomes of Acute Heart Failure: PEACE MENA Registry Phase I Results.

INTRODUCTION: PEACE MENA (Program for the Evaluation and Management of Cardiac Events in the Middle East and North Africa) is a prospective registry in Arab countries for in-patients with acute myocardial infarction (AMI) or acute heart failure (AHF). Here, we report the baseline characteristics and outcomes of in-patients with AHF who were enrolled during the first 14 months of the recruitment phase. METHODS: A prospective, multi-centre, multi-country study including patients hospitalized with AHF was conducted. Clinical characteristics, echocardiogram, BNP (B-type natriuretic peptide), socioeconomic status, management, 1-month, and 1-year outcomes are reported. RESULTS: Between April 2019 and June 2020, a total of 1258 adults with AHF from 16 Arab countries were recruited. Their mean age was 63.3 (±15) years, 56.8% were men, 65% had monthly income ≤US$ 500, and 56% had limited education. Furthermore, 55% had diabetes mellitus, 67% had hypertension; 55% had HFrEF (heart failure with reduced ejection fraction), and 19% had HFpEF (heart failure with preserved ejection fraction). At 1 year, 3.6% had a heart failure-related device (0-22%) and 7.3% used an angiotensin receptor neprilysin inhibitor (0-43%). Mortality was 4.4% per 1 month and 11.77% per 1-year post-discharge. Compared with higher-income patients, lower-income patients had a higher 1-year total heart failure hospitalization rate (45.6 vs 29.9%, p=0.001), and the 1-year mortality difference was not statistically significant (13.2 vs 8.8%, p=0.059). CONCLUSION: Most of the patients with AHF in Arab countries had a high burden of cardiac risk factors, low income, and low education status with great heterogeneity in key performance indicators of AHF management among Arab countries.

The Impact of Uncontrolled Hypertension on the Longitudinal Systolic Function of the Left Ventricle.

BACKGROUND: The assessment of the longitudinal component of left ventricular (LV) function is of major clinical importance for the early detection of LV contractile impairment. The aim of this study was to determine the impact of uncontrolled hypertension, on LV longitudinal systolic performance. METHODS: The study population included 400 hypertensive patients: 271 patients with uncontrolled blood pressure (BP) and 112 without controlled BP, all patients underwent a complete ultrasound evaluation with the calculation of the LV mass, evaluation of diastolic function as well as longitudinal systolic function. RESULTS: Conventional echo demonstrated that uncontrolled patients had increased LV mass (P 0.007), LA (left auricular) dimension (P 0.004), left ventricular wall thickness and impairment of diastolic function (E/E'6 ± 2.1 vs 7.4 ±3.0 P=0.001) while no affection of systolic function could be detected. By deformation imaging, there was a reduction in longitudinal strain (apical 4 view -16.2 ±2.9 vs -18.2± 2.6 P 0.02, apical 3 view -17.3 ± 3.3 vs. -18.9 ± 4.1 P 0.01). Similarly, systolic strain rate (SRsys) and early diastolic SR (SRe) reduced significantly in longitudinal direction. CONCLUSION: Although EF was not different between uncontrolled patients and controls, LV longitudinal strain and strain rate by 2D speckle tracking were lower in the uncontrolled group.

Impact of Diabetes on Cardiac Function in Patients with High Blood Pressure.

Background: Although the combination of high blood pressure (HBP) and type 2 diabetes (T2DM) increases the risk of left ventricular (LV) dysfunction, the impact of T2DM on LV geometry and subclinical dysfunction in hypertensive patients and normal ejection fraction (EF) has been infrequently evaluated. Methods: Hypertensive patients with or without T2DM underwent cardiac echocardiography coupled with LV global longitudinal strain (GLS) assessment. Results: Among 200 patients with HBP (mean age 61.7 ± 9.7 years) and EF > 55%, 93 had associated T2DM. Patients with T2DM had a higher body mass index (29.9 ± 5.1 kg/m2 vs. 29.3 ± 4.7 kg/m2, p = 0.025), higher BP levels (158 ± 23/95 ± 13 vs. 142 ± 33/87 ± 12 mmHg, p = 0.003), a higher LV mass index (115.8 ± 32.4 vs. 112.0 ± 24.7 g/m2, p = 0.004), and higher relative wall thickness (0.51 ± 0.16 vs. 0.46 ± 0.12, p = 0.0001). They had more frequently concentric remodeling (20.4% vs. 16.8%, p < 0.001), concentric hypertrophy (53.7% vs. 48.6%, p < 0.001), elevated filling pressures (25.8 vs. 12.1%, p = 0.0001), indexed left atrial volumes greater than 28 mL/m2 (17.2 vs. 11.2%, p = 0.001), and a reduced GLS less than -18% (74.2 vs. 47.7%, p < 0.0001). After adjustment for BP and BMI, T2DM remains an independent determinant factor for GLS decline (OR = 2.26, 95% CI 1.11-4.61, p = 0.023). Conclusions: Left ventricular geometry and subclinical LV function as assessed with GLS are more impaired in hypertensive patients with than without T2DM. Preventive approaches to control BMI and risk of T2DM in hypertensive patients should be emphasized.

Children hypertension in Northern Africa.

OBJECTIVES: To assess factors associated with prehypertension and hypertension among children in North Africa. METHODS: An epidemiological observational, school- and college-based study among 3562 healthy children and adolescents to assess factors associated with blood pressure categories (normal, prehypertensive, hypertensive), including perinatal (gestational age, birth weight, breastfeeding) and current lifestyle characteristics (body mass index, time spent watching a screen and time spent exercising). RESULTS: Prevalence of hypertension increased with age from 8.7% between 6-10 years to 14.7% between 11-15 years, and 15.6% above 15 years. Prevalence of prehypertension and hypertension increased with body mass index from 9.9% and 11.5% among children not overweight to 15.6% (RR 1.58, 95% CI 1.24-2.02, P<0.001) and 17.2% (RR 1.50, 95% CI 1.22-1.85, P<0.001) among those overweight and to 26.8% (RR 2.72, 95% CI 2.04-3.64, P<0.01) and 32.3% (RR 2.82, 95% CI 2.27-3.50, P<0.01) among obese children. There was a trend of association of prehypertension with the time spent watching Television, internet and electronic games. Children whose mother or father had a history of hypertension had a trend to be prehypertensive or hypertensive. A parental hypertension was found in 33.6% of normotensive, 38.2% of prehypertensive, and 42.6% of hypertensive children (P=0.05). Children with prehypertension or hypertension were more likely to have a diabetic father or mother (22.8% and 22.6% vs 15.8%, respectively, P=0.01). Also, prehypertension and hypertension were associated with shorter gestational age, early birth, reduced birth weight, and shorter breastfeeding. CONCLUSION: Prehypertension and hypertension have a high prevalence among children in North Africa. They are associated with overweight, obesity, diabetes, a shorter gestational age, a lower birth weight and a shorter breastfeeding.

Ambulatory Blood Pressure Monitoring in the Diagnosis and Management of Arterial Hypertension in Current Medical Practice in Algeria.

OBJECTIVE: There are limited data on the management of hypertension (HT) in Algeria. The aim of this study was to assess, in current medical practice, the use and benefits of ambulatory blood pressure monitoring (ABPM) for the diagnosis and management of HT. METHODS: A prospective, observational, multicenter study was performed in 2017. Patients aged ≥ 18 years with suspected or treated HT were included. A 24-hour ABPM was performed at baseline in all patients. Therapeutic decision was taken by the physician according to ABPM results and patients were then followed up to 6 weeks. RESULTS: The analysis included 1027 patients (mean age, 51.0 years; women, 61.6%) with treated HT (37.3%) or suspected HT (62.7%). Major cardiovascular risk factors were diabetes (15.7%) and lipid disorders (7.2%). ABPM was pathological in 55.1% of patients on antihypertensive treatment and in 60.8% of patients with suspected HT. A therapeutic adjustment or a treatment switch was performed after pathological ABPM in 37.4% of patients already on antihypertensive treatment and an antihypertensive therapy was initiated in 54.9% of patients with initially suspected HT. CONCLUSION: This study is the first evaluation of the usefulness of ABPM for the management of HT in Algeria. Our results emphasize that ABPM is a highly valuable method for avoiding the whitecoat effect and for detecting patients who are insufficiently treated with antihypertensive drugs.

Intracoronary or intravenous abciximab after aspiration thrombectomy in patients with STEMI undergoing primary percutaneous coronary intervention.

OBJECTIVE: To test whether aspiration thrombectomy with intracoronary (IC) instead of intravenous (IV) administration of abciximab could reduce the no-reflow phenomenon in patients undergoing primary percutaneous intervention (PCI) for ST-elevation myocardial infarction (STEMI). BACKGROUND: Despite recanalisation with PCI, failure to restore microvascular flow may affect the prognosis of patients with STEMI. A combination of aspiration thrombectomy with IC abciximab may improve distal perfusion. METHODS: After aspiration thrombectomy during primary PCI for STEMI, 160 patients were randomly assigned to either an IV or IC abciximab bolus delivered through the aspiration catheter, both followed by a 12-hour IV abciximab infusion. RESULTS: ST-segment resolution ≥ 70% was achieved in 36 of 78 patients with IC versus 30 of 82 patients with IV abciximab (46.1 vs 36.6%, p = 0.368), and partial resolution in 28 of 78 versus 31 of 82 patients (35.9 vs 37.8%, p = 0.368). Postprocedural myocardial blush grade (MBG) 3 was obtained in 62.8 vs 63.4% (p = 0.235) and MBG ≥ 2 in 89.7 vs 81.7% (p = 0.148) of patients given IC and IV abciximab, respectively. There were three deaths in each group (3.8%). Major adverse cardiac events occurred in six of 78 patients given the IC and seven of 82 patients given the IV abciximab bolus (7.6 vs 8.5%, p = 0.410). One stroke occurred in each group, and two patients in the IC and nine in the IV group developed renal failure (2.5 vs 10.9%, p = 0.414). CONCLUSIONS: IC versus IV abciximab did not enhance myocardial reperfusion in non-selected patients with STEMI undergoing primary PCI after aspiration thrombectomy had successfully been performed.

Factors associated with global longitudinal strain decline in hypertensive patients with normal left ventricular ejection fraction.

Background Early detection of risk factors for left ventricular (LV) dysfunction may be useful in patients with high blood pressure (HBP). Methods Patient from an outpatient HBP clinic underwent a two-dimensional Doppler-coupled echocardiography with determination of LV global longitudinal strain (GLS) by speckle-tracking. Results Among 200 patients (mean age 61.7 ± 9.7 years), 155 were overweight, 93 had diabetes, 83 had dyslipidemia, and 109 had uncontrolled HBP. LV hypertrophy (LVH) was found in 136 patients (68%), including concentric ( n = 106) and eccentric ( n = 30) LVH. Diastolic dysfunction patterns were observed in 178 patients (89%), and increased filling pressures were observed in 37 patients (18.5%). GLS ranged from -25% to -11.6% (mean -16.9 ± 3.2%). Low GLS values (>-17%) were found in 91 patients (45.5%), 68 with and 23 without LVH. In univariate analysis, a reduced GLS was associated with HBP lasting for >10 years (odds ratio (OR) = 3.51, 95% confidence interval (CI) 1.73-7.09; p = 0.002), uncontrolled HBP (OR = 3.55, 95% CI 1.96-6.43; p < 0.0001), overweight (OR = 2.01, 95% CI 0.93-4.31; p = 0.0028), diabetes (OR = 2.21, 95% CI 1.25-3.90; p = 0.006), dyslipidemia (OR = 2.16, 95% CI 1.22-3.84; p = 0.008), renal failure (OR = 4.27, 95% CI 1.80-10.10; p = 0.001), an increased Cornell index (OR = 3.70, 95% CI 1.98-6.90; p < 0.0001), concentric LVH (OR = 9.26, 95% CI 2.62-32.73; p = 0.001), remodeling (OR = 8.51, 95% CI 2.18-33.23; p = 0.002), and filling pressures (OR = 7.1, 95% CI 2.9-17.3; p < 0.0001). In multivariable analysis, duration of HBP ( p = 0.038), uncontrolled BP ( p = 0.006), diabetes ( p = 0.023), LVH ( p = 0.001), and increased filling pressures ( p = 0.003) remained associated with GLS decline. Conclusion Early impairment of LV function, detected by a reduced GLS, is associated with long-lasting, uncontrolled HBP, overweight, related metabolic changes, and is more pronounced in patients with LVH.

Impact of platelet inhibition level on subsequent no-reflow in patients undergoing primary percutaneous coronary intervention for ST-segment elevation myocardial infarction.

BACKGROUND: High P2Y12 platelet reactivity (PR) level after primary percutaneous coronary intervention (PPCI) for ST-segment elevation myocardial infarction (STEMI) affects prognosis and may induce the no-reflow phenomenon. AIM: To investigate the role of PR in the genesis of microvascular obstruction. METHODS: Patients with STEMI undergoing PPCI within 12hours of symptoms onset were included prospectively. All patients received a 600mg clopidogrel-loading dose before PPCI and 250mg aspirin. PR was measured thereafter during PPCI while wiring the culprit lesion and before coronary dilatation, using the P2Y12 VerifyNow® assay. No-reflow was defined as ST-segment regression<50% observed 90minutes after PPCI. RESULTS: Between January 2014 and November 2015, 140 STEMI patients were included, and divided into two groups: a low PR group (LPR) defined as PR<209P2Y12 reaction units (PRU); and a high PR group (HPR) defined as PR≥209PRU. There were no differences in baseline characteristics between LPR and HPR groups, including age (57.8±11.9 vs. 59.4±13.2 years, respectively; P=0.44) and weight (76.1±15.1 vs. 74.8±10.9kg, respectively; P=0.55). Delay to revascularization was 270.1±175.5 vs. 295.6±206.2minutes (P=0.49) and time between clopidogrel-loading and PR measurement was 53±37 vs 65±54minutes (P=0.29) in the LPR and HPR groups, respectively. No-reflow was more frequent in the HPR group (44 [47.3%] vs. 9 [19.1%]; P=0.0012). Mean PR was higher in patients with no-reflow: 268.3±53 vs. 223.8±50.1 PRU (P=0.002). In multivariable analysis, HPR was an independent predictor of no-reflow. Area under the receiver operating characteristic curve was 0.745 (0.654, 0.835); the cut-off value predicting no-reflow was 254PRU. CONCLUSION: High PR level measured at PPCI is independently associated with no-reflow.

Assessment for Pulmonary Artery Hypertension Using Clinical and Echocardiographic Criteria in Patients With Systemic Sclerosis.

BACKGROUND: Prognosis of systemic sclerosis (SSc) is affected by pulmonary artery hypertension (PAH). METHODS: Among 202 patients (mean age: 46.1 ± 13.3 years; 177 women) with SSc, those with a tricuspid regurgitation (TR) jet maximal velocity at 2D-echocardiography (2DE) < 2.8m/second were not considered at high risk for PAH, whereas those with a TR velocity >3m/second or between 2.8 and 3m/second and associated with dyspnea were. RESULTS: Among 22 patients at risk, 15 (mean age: 50.4 ± 14.3 years) had definite precapillary PAH on right heart catheterization (RHC). The delay period between recognitions of SSc and PAH was 12.9 ± 5.2 years. Dyspnea was present in all 15 patients, 11 (73.3%) being in the New York Heart Association class III or IV. The 2DE showed normal left ventricular geometrics and function (n = 15), enlargement of the right-sided cardiac chambers (n = 12), increased pulmonary arterial resistances with a TR velocity to pulmonary time-velocity integral ratio of > 0.2 (n = 15) and impaired right ventricle function (n = 15). RHC showed severe PAH in all 15 patients (mean pulmonary artery pressure: 48 ± 17mmHg and mean right atrial pressure: 11.8 ± 4.4mmHg) and a reduced cardiac index (2.2L/m²). There was no statistical difference between patients with and without PAH regarding age, sex ratio, duration from onset of disease, diffuse or cutaneous limited type of SSc, Rodnan severity score and presence of digital ulcerations or autoantibodies. Telangiectasia (P = 0.01) and New York Heart Association class III or IV heart failure (P = 0.001) were more frequent in patients with PAH. CONCLUSION: A combined clinical and Doppler-coupled 2DE screening of PAH risk in patients with SSc is useful to select those who can undergo RHC.

Role of birth weight and postnatal growth on pulse wave velocity in teenagers.

PURPOSE: Low birth weight and accelerated postnatal growth appear to play a significant role in the pathogenesis of hypertension and cardiovascular disease in adulthood. The aim of the present study was to characterize the factors determining pulse wave velocity (PWV) in teenagers and, in particular, to verify the relationship with birth weight, postnatal growth, timing of adiposity rebound, lifestyle, and hemodynamic parameters. METHODS: Carotid-femoral and carotid-radial pulse wave velocities of 558 healthy teenagers (age range: 16.2-19.9 years) were determined by means of a PulsePen tonometer. Birth weight and gestational age were obtained from obstetrical records, and data regarding postnatal growth were obtained from pediatric clinical records. RESULTS: No change in aortic PWV was found in association with birth weight, postnatal growth, and timing of adiposity rebound. However, the study showed a strong association between accelerated growth from 0 to 12 months and carotid-radial PWV (trend: p = .02). Subjects with birth weight values <2,500 g showed higher values of upper limb PWV (p < .05) and higher values of diastolic and mean arterial pressure (p < .05). Stepwise regression analysis revealed that mean arterial pressure, age, and height were the main independent factors determining aortic PWV in this young population. CONCLUSIONS: These results suggest that there is no linear correlation between birth weight and hemodynamic parameters in teenagers; however, subjects characterized by very low birth weight and accelerated postnatal weight gain appear to demonstrate increased upper limb PWV and diastolic and mean arterial pressure values.

Prevalence and determinants of hypertension in the Algerian Sahara.

BACKGROUND: In-Salah is a city-oasis located in the middle of the Algerian Sahara, a desert area whose drinking water has a high sodium content. No cardiovascular epidemiological studies have ever been conducted in this region. METHODS: A randomized sample of 635 men and 711 women, aged 40-99 years, was studied. Blood pressure measurements, combined with a clinical questionnaire that included educational and socio-economic data, and standard blood samples for the detection of dyslipidemia and diabetes mellitus, were collected. RESULTS: The mean age was 55 +/- 12 years. The prevalence of hypertension was 44% and was highly influenced by age, sex, skin colour, educational status, obesity and metabolic parameters. The higher prevalence of hypertension among black individuals was independent of socio-economic and educational levels, and of metabolic parameters. The presence of antihypertensive treatment was three times more frequent in women than in men, and there was no difference according to skin colour. Among treated subjects, 25% were well controlled, and this percentage was similar among both black and white individuals. CONCLUSION: Epidemiological studies in such an emergent population indicate that hypertension is a major public health problem. The high sodium content in drinking water in this region could play a major role in the development of hypertension.
