Background: The aim of the study was to evaluate the incidence of Coronary artery disease (CAD) and predictors of CAD in patients with severe AS in western Rajasthan population.Methods: Data from all consecutive patients with severe AS undergoing AVR at a major tertiary cardiac and vascular center in Udaipur were entered in a prospective registry beginning in 2015. Significant CAD was defined as one or more major coronary arteries having an estimated narrowing of ≥70% and left main coronary arteries having an estimated narrowing of ≥50% on coronary angiography. We excluded patients with multiple valve disease, significant aortic regurgitation, or prior CAD or valve surgery.Results: Mean age of 55 enrolled patients was 52.64±15.5 years. Diabetes mellitus and hypertension were present in 3.64% and 5.45% of patients, respectively. Moderate and severe Left ventricular ejection fraction (LVEF) was found in 16.36% and 10.91% patients, respectively. Only 5.45% patient had severe CAD and thus underwent AVR and coronary artery bypass grafting, and rest 94.55% patients underwent AVR. Mean age of patients who underwent AVR was 51.75±15.36 years and who underwent AVR and CABG was 68±11.14 years with no significant association (p=0.078). Proportion of patients requiring AVR and CABG was significantly higher in moderate (22.22%) and severe LVEF (16.67%) as compared to normal or mild (p=0.034).Conclusions: Coronary angiography before AVR will be considered in patients with multiple risk factors for cardiovascular disease or in patients above 68 years of age without risk factors for cardiovascular disease. However, larger studies on heterogeneous population are required to prove our findings.

Takotsubo syndrome is an acute and often reversible condition, with initial presentation mimicking acute coronary syndrome. Typically, patients present with left ventricular regional wall motion abnormalities, without a corresponding coronary artery obstruction on angiography. Coexistence of a coronary artery disease is possible and may render the distinction between the two entities particularly challenging. We report the case of a 94-year-old woman with chest pain after an emotional upset and acute myocardial injury. Transthoracic echocardiogram (TTE) revealed a severely reduced left ventricular ejection fraction (LVEF) with apical ballooning. Coronary angiogram showed significant stenosis of the distal left main coronary artery and of the mid-left anterior descending artery, as well as a 30%–50% stenosis of the mid-distal right coronary artery. Revascularisation was deferred and antiplatelet as well as heart failure therapy begun. A repeat TTE 6 days later revealed a quasi-normalised LVEF. Ultimately, percutaneous coronary revascularisation of the left main and left anterior descending artery was performed, with favourable outcome at 6-month follow-up.

Introduction: The risk factors for aortic stenosis have been shown to be similar to those for atherosclerosis. Thus, coronary disease is often found simultaneously in patients with aortic stenosis. Our work aims to determine the frequency of coronary disease in a Moroccan population with aortic stenosis while recalling the causes and the prognostic and therapeutic impacts of this association. Materials and Methods: This is a retrospective study of 148 patients hospitalized at the cardiology center of the military hospital of Rabat over a period of 24 months, during which we analyzed clinical, electrocardiographic, echocardiographic and coronarographic data of the patients in order to evaluate the coronary involvement during aortic stenosis. Results: The mean age of the population was 65 [57, 74] years, the sex ratio was 1.21. Smoking reported in 38.5% of patients was the main modifiable cardiovascular risk factor, followed by hypertension in 35.8% of patients. Dyspnea on exertion was the most frequent reason for consultation at 81%, 64% of which were at least NYHA functional class III, followed by angina, which represented 33% of the series. The aortic stenosis was tight in the majority (mean SAo: 0.8 cm²) and the left ventricular ejection fraction was preserved overall. Coronary artery disease was associated with aortic stenosis in 24% of cases, with predominantly monotruncal involvement (53%) followed by tritruncal involvement (30%). 21.6% of these patients underwent coronary artery bypass grafting concomitantly with surgical replacement of the aortic valve. Conclusion: The incidence of coronary artery disease associated with aortic stenosis is variable according to age. It is higher in European series because of aging. In our relatively younger population, it is lower but not negligible.

Numerous studies have demonstrated the negative prognostic value of tachycardia, both in the general population and in specific subgroups, including patients with coronary artery disease (CAD), arterial hypertension (HTN) and heart failure with preserved ejection fraction (HFpEF). In the latest edition of the European guidlines for the treatment of HTN the level of heart rate (HR) exceeding 80 beats per minute is highlighted as a separate independent predictor of adverse outcomes. However, the feasibility of pharmacological reduction of HR in patients with sinus rhythm is unclear. Unlike patients with reduced ejection fraction, in whom the positive effects of HR reduction are well established, the data on the effect of pharmacological HR reduction on the prognosis of patients with HTN, CAD and/or HFpEF are not so unambiguous. Some adverse effects of pharmacological correction of HR in such patients, which may be caused by a change in the aortic pressure waveform with its increase in late systole in the presence of left ventricular diastolic dysfunction, are discussed. The reviewed data underline the complexity of the problem of clinical and prognostic significance of increased HR and its correction in patients with HTN, stable CAD and/or HFpEF.
